Let f(x) = A sin ((2pi/B)*X)
.The graph of this function has a tangent line with a slope of 4
at the point (B/8 , 1)
find the exact values of a and b
so for a i put in B/8 for x and 1 for y and cancled out the b's and got
a= 1/sin(pi/4)
then for b do i find the derivative and make that = 4?
or is b infinate?
