Price Elasticity of Demand from a Given Demand Function

[@palaksrivastava2805]

couldn't find vidoes on this topic other than yours. Explained very nicely

[@ECONMATHS]

My pleasure

I need few more plzz help

Thanks for easy explanation.

Amazing video sir !! Thank you

Consider aperefertly competitive market in the short run assume that market demand is p=100-4Qd and market supply is p=Qs TFC =50 mc= 8q+12q2

[@ECONMATHS]

so what to find

[@M_Sefat]

Thanks a lot sir

(ii) Calculate Price Elasticity of Demand (PED) when price rises from R20 to R80.

thanks

Thanks for the appreciation

Demand function p=40-Q^2 .Calculate the value of elasticity( Ed). when p=20.

[@siya_javheri]

Hey hey... Answer this one too.
. Comment on elasticity of demand of a commodity for p = 600 when demand function is p=(1200- q²/2)

[@ECONMATHS]

Hay Hay

[@insonsokoni2384]

Kindly help me answer this question.
Given a demand function of Q = 20 -2P, find the price range for which;
A) Demand is elastic
B) Demand is inelastic
C) Demand in unitary elastic
D) If this firm increases price to K7, will total revenue increase or decrease?

What kind of commodity is commodity X

[@priyanshirathi1107]

Sir, 0-10 = -10

He corrected it later😊

[@GMSPK]

Good

[@itzRoCkY465]

Absolute value of price elasticity demand is. -dq/dp•p/q. Then what happen with minus sign in price elasticity demand formula???

[@ECONMATHS]

We take the absolute value of the number , so minus sign vanishes out

[@darmukhtar2616]

Nice

[@shingiemurombedzi2928]

help me on this....a goood has an elasticity of demand of 2 and demand curve of P=150-1.2Q find price and quantity

[@hillary3066]

So its elastic since its greater than 1?

[@soumyamunegowda361]

Sir I need answer for the question below
Q= 15S*1/2P*-3 where S= 10 find price elasticity of demand.

[@ECONMATHS]

Can't understand the question

[@Priya_Singh25]

Sir what will be elasticity of demand in terms of x for demand function P=10/(x+1)^2.

[@ECONMATHS]

E= -root(10) * 0.5 p ^ -3/2 * p/x

[@ECONMATHS]

It would be in general form

[@ghmohd219]

[@RAVIKUMAR-ky2rc]

Sir I couldn't understand the dq/dp=10

[@ECONMATHS]

This is from the rules of differention . Please check the playlist on this channel 'differentiation in economics'

[@RAVIKUMAR-ky2rc]

Ok sir

[@ADRMEENA]

minus minus plus ???? in last solution .. so, -30/80 .

[@gilbertcheruiyot9677]

How about when its vise versa...
The function being P=100-4q at a point where P=20

[@ECONMATHS]

Then first solve it for q . 4q=100-p
q= 25-0.25q

[@richachandra518]

@@ECONMATHS q = 25 - 0.25 p

[@ghmohd219]

Excellent video

[@joeyberonio3414]

I don't understand how did you get that dp dq to 0-10

[@ECONMATHS]

q=500-10p
dq/dp = 0 -10
rules of differentiation tells us that the derivative of any constant like 1, 2, 3 , pi , etc is zero
Derivative of p wrt q is simply
1* p¹-¹ = 1* p^0 = 1 * anything raised power 0 is 1
So derivative of 10p is 10
