(15 pts) Use Logarithmic differentiation to find the derivative of the function, y = (cos(x))"() , and write your answer in term of x.Find each derivative. If it does not exist, write DNE. i. (3 pt) f' (0) y 8- i. (2 pt) f' (3) sin (2x) 0 X (5 pts) Find lim x-+0 tan ( 5x) (Can't use L'Hospital's Rule)(15 pts) Find % and the equation of the tangent line on the curve parametrized by x t = t2 +1 { ( ) where the tangent line has slope 1. (Use exact values and write the equations in slope- y(t)=t2t 2 intercept form)
