I need help on these 5 calculus questions:

Question 13 (1 point) COs X The derivative of edt is sin x O1 Ocos(x) esin(x) + sin(x)ecos(x) O ecos(x) _ sin(x) O-cos(x)esin(x) - sin(x)ecos(x) O esin(x) + pcos(x)\fQuestion 15 (1 point) 5 Let p be a constant. For what value(s) of p is the integral dx improper? x - P (i.e. for what p value(s) would we need to use the "Improper Integrals - Type 2" techniques to solve?) Op = 1 and p = 5 only. Op = 0 only. This integral is never improper. The integral is improper for all p on (-co, co). All p on the interval [1, 5] only
