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.

1. f(x) =x/√7-3x Note: The square root is over 7-3x.

2. y = xsin1/x

3. f(t) =√t/t^2+4 Note: The square root is over t/t^2+4.

4. y = [x^2+(1-3x)^5]^3.

5. sin(sin(sinx)).

6. y = √x+√x Note: The first square root is over x+√x.
