Thank you for this video. This video not only taught me how to graph trig functions in Scratch, but it also taught me trigonometry. Keep up the good work bro!👍🏻👍🏻👍🏻

[@Histtries_Mapper]

THIS IS UNBELIEVABLE, THANK YOU SO MUCH THIS IS VERY HELPFUL, I didn't expect that sine, cosine and tan can do this too!

[@zero-fc9ol]

Thank you so much Sir 👍

[@dockpirate2127]

what I've been waiting for

[@vysyogh]

VERY EDUCATIVE SIR

[@Roryrex]

I Like Using The Timer Instead Of A Variable. Bit I Like Your Idea A Lot Too :)

[@SurfingScratcher]

Awesome idea!

[@Roryrex]

@@SurfingScratcher Thanks :D

[@user-yg9fy7od7f]

But@@Roryrex, what if you are using the reset timer block fo making the when stop sign clicked?

[@percosey]

Cool

[@CoolScratcher]

YES

[@bozza_da_swish]

How do you move around a circle using tangents?

[@SurfingScratcher]

If we inspect the values of sin, cos and tan, can you see how sin and cos have a relationship together whereas tan is more standalone? Using SOH, CAH, TOA, you could use TOA to help you draw a circle, but I think it's the more complicated route.

[@SurfingScratcher]

Further, Sin and Cos act more like percentages with limits between -1 and 1. That's how we can use them to plot x and y values. Tan has no limit. It counts up to infinity and down to negative infinity. It has no limits for us to play with.

[@bozza_da_swish]

@@SurfingScratcher thanks a lot for the reply. I understand using tangents is a more complicated route ...but I need your help programming a Mine truck to navigate around a curve using trigonometry, how best would you approach this problem? N.B The truck needs to rotate as it navigates around the curve(half circle).

[@SurfingScratcher]

@@bozza_da_swish For basic curves using oval shapes, you just have different rates of change with x and y values. If you change y values more than x values, you'll get an oval that's taller. If you change the x value more than y, then you'll get a wider circle.
If you need something more complicated like calculating a curve between two points, then you probably want to research bezier curves and their forumlas.

5TH COMMENT YO!!!!

[@vysyogh]

SCRATCH TO REPORTS NOT INFINITY FOR TAN 90 BUT A HUGE NUMBER

[@thomasmarilon7737]

the intro tho

[@pizzaizgreat]

Is it just me thinking tan looks like a heatbeat

[@SurfingScratcher]

Life is a wave!

[@catto9207]

You need to change to unity or something thats the way you got more subs
