Fought the whole semester to keep my A, this is what's going to blow it for me. This stuff makes absolutely zero sense without a reference sheet or something.
I'm 9th grade. These are simple especially with proof which is given in the vid in the description. You haven't tried finding the derivatives of the hyperbolics of these. Say goodbye to numbers.
Thanks, man. Been cramming right before finals trying to relearn everything, and this channel has been a life saver. Everything is explained so clearly and simply it makes trig seem easy.
Donkey A and Donkey B are walking toward each other on a dirt road. Donkey A starts from the barn, 15 miles away from the meeting point, at 1:00 PM. Donkey B starts from the orchard, 10 miles away from the meeting point, at the same time, 1:00 PM. Donkey A walks at a speed of 3 miles per hour, while Donkey B walks at a speed of 2 miles per hour. At what time will Donkey A and Donkey B collide?
@@wege8409 To determine the time when Donkey A and Donkey B collide, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Combined Speed}} \] ### Step 1: Calculate the combined speed - Donkey A's speed: 3 miles per hour - Donkey B's speed: 2 miles per hour - Combined speed: \( 3 \text{ miles per hour} + 2 \text{ miles per hour} = 5 \text{ miles per hour} \) ### Step 2: Calculate the total distance between them - Donkey A starts 15 miles away from the meeting point. - Donkey B starts 10 miles away from the meeting point. - Total distance: \( 15 \text{ miles} + 10 \text{ miles} = 25 \text{ miles} \) ### Step 3: Calculate the time it takes for them to collide \[ \text{Time} = \frac{25 \text{ miles}}{5 \text{ miles per hour}} = 5 \text{ hours} \] ### Step 4: Determine the collision time Since they both start at 1:00 PM, they will collide 5 hours later: \[ 1:00 \text{ PM} + 5 \text{ hours} = 6:00 \text{ PM} \] So, Donkey A and Donkey B will collide at **6:00 PM**.
@@wege8409 Let's break this down step by step: 1. Donkey A starts 15 miles away from the meeting point and walks at 3 miles per hour. To find the time it takes for Donkey A to reach the meeting point, divide the distance by the speed: 15 miles / 3 miles per hour = 5 hours 1. Donkey B starts 10 miles away from the meeting point and walks at 2 miles per hour. To find the time it takes for Donkey B to reach the meeting point, divide the distance by the speed: 10 miles / 2 miles per hour = 5 hours 1. Since both donkeys start at the same time (1:00 PM) and take the same amount of time to reach the meeting point (5 hours), they will collide at: 1:00 PM + 5 hours = 6:00 PM So, Donkey A and Donkey B will collide at 6:00 PM.

Next year ill be taking calc for my senior year in high school so i decided to put in the hours this summer. i am 8 mins into this video i can feal an increasing pressure in my skull and that's a good thing cause am absorbing the information. But its unreal its all of this is packed into a
I studied all this with great interest while studying in college. But now after 13 years it was very difficult to recollect. So when I go for an interview for the position of a mathematic teacher to answer the trigonometric functions was a difficult task. But this video helped me to remember all the trigonometric functions. It is really helpful for me. Thank you so much.
i got a test tomorrow in pre calc on trig as a whole. i need to be able to graph all trig functions, all inverses, know all trig indentities. i need to know when functions are odd or even for graphing. i need to know inverse trig functions and inverse trig relation. Right now I currently don’t know anything other than graphing a sin graph. Hopefully an All nighter saves me
how do u know when to apply a trig identity? is it necessary to apply an identity everytime u see one, or are there times where leaving the trig expression just as it is is better than applying an identity?
I can handle any mathematics up to calc 3, but I still get these trig identities wrong. I have got to figure out a system to really commit these to memory because I should not be having this problem.

@@wege8409 To determine the time when Donkey A and Donkey B collide, we can use the formula:

### Step 1: Calculate the combined speed
- Donkey A's speed: 3 miles per hour
- Donkey B's speed: 2 miles per hour
- Combined speed: \( 3 \text{ miles per hour} + 2 \text{ miles per hour} = 5 \text{ miles per hour} \)
### Step 2: Calculate the total distance between them
- Donkey A starts 15 miles away from the meeting point.
- Donkey B starts 10 miles away from the meeting point.
- Total distance: \( 15 \text{ miles} + 10 \text{ miles} = 25 \text{ miles} \)
### Step 3: Calculate the time it takes for them to collide
\[
\text{Time} = \frac{25 \text{ miles}}{5 \text{ miles per hour}} = 5 \text{ hours}
\]
### Step 4: Determine the collision time
Since they both start at 1:00 PM, they will collide 5 hours later:
\[
1:00 \text{ PM} + 5 \text{ hours} = 6:00 \text{ PM}
\]
So, Donkey A and Donkey B will collide at **6:00 PM**.

10 miles / 2 miles per hour = 5 hours
1. Since both donkeys start at the same time (1:00 PM) and take the same amount of time to reach the meeting point (5 hours), they will collide at:
1:00 PM + 5 hours = 6:00 PM
So, Donkey A and Donkey B will collide at 6:00 PM.
