a) Provided that sin x= 5/13, cos y = (-3/5), and both x and y are in quad II. Find exact value of tan(x+y)
b) write down sin(pi/4 + arcsin x) as the algebraic expression
c) write down cos(arcsin x + arccos x) as the algebraic expression
d.) write down sin[arcisn(x/2) - arccos(x/3)] as the algebraic expression
