Question

Sin alpha + beta where sin alpha equals to 3 by 5 and cos beta equals to 5 by 13 a alpha and beta in quadrant 1

Answer 1

Answer:

If cos (alpha+beta) = 4 / 5, sin (alpha+beta) = 5 /13 and (alpha) and (beta) lies between 0 and pi / 4, show that tan 2(alpha) = 56 / 33......................

Answer 2

Answer:

If cos (alpha+beta) = 4 / 5, sin (alpha+beta) = 5 /13 and (alpha) and (beta) lies between 0 and pi / 4, show that tan 2(alpha) = 56 / 33......................
