Question says-
find the derivatives of: d/dt t^(-pi^2)
Steps:
have no clue how to do this.
And then find the equation of the tangent line to y=4e^x at x=2?
Steps: derivative of y= 4e^x. Plug 2 in for x and then I find the slope of the tangent line which is 29.556
Then to find the equation I have slope m, and x=2. How do I find y to find the equation?
Please help!!
