Calculus
Consider the area between the graphs x+1y=12 and x+8=y2 . This area can be computed in two different ways using integrals First of all it can be computed as a sum of two integrals Interval a to b f(x)= i put 12x but it's wrong Interval c to b f(x)= i put

Implicit Differentiation
Find the slope of the tangent line to the curve (a lemniscate) 2(x^2+y^2)^2=25(x^2–y^2) at the point (–3,1) . I know that we are supposed to use chain rule for this problem but i think i am messing up on the algebra. Can someone please help me, i keep

Calculus: Area
Can someone look at my work and see what i did wrong. I did this 100 times but i keep getting it wrong Sketch the region enclosed by the given curves. Decide whether to integrate with respect to x or y. Then find the area of the region. 2y=3x^(1/2) , y=4

Implicit Differentiation
Use implicit differentiation to find the slope of the tangent line to the curve y/x+6y=x^2–6 at the point (1,–5/31) . Again i think i'm messing up with the algebra here. I used quotient rule to get [(x+6y)(y')(y)(1+6y')]/(x+6y)^2=2x I don't know how

Implicit Differentiation
Oh my goodness, thank you soooo much for writing it out i totally wasn't getting it! THank you so much :) Do you think you coul check my arithmatic for another problem? It's Use implicit differentiation to find the slope of the tangent line to the curve

Implicit Differentiation
I got y'=(2x+x^2+12yx+6y^2y)/(x+6y+6) But when i plugged in the numbers it came out right... do you think the equation is wrong or i just typed in the numbers wrong? BTW thanks for replying!
