Calculus

1.

A.) Find an equation of the tangent line to the curve y = tan(πx^2/4) at the point (1,1). Note: π is the pi sign.

B.) Illustrate part (A) by graphing the curve and the tangent line on the same screen.

2.

Find all point on the graph of the function
f(x) = 2sinx+sin²x at which the tangent line is horizontal.

Re: Calculus

IMMORTALX,

post all of your work/attempts at the problems
first so that you may be helped where you are
stuck.  Your input is needed, and none of the
answers on any of your threads should just be
delivered to you.  We're to be coaches, and
you're to be the athlete who does the work/practice
so you can be guided in a better direction.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
