If `alpha and beta` are complementary angles then `sin^2 (90^@ – alpha)+sin^2 (90^@-beta)`

If alpha , beta are complementary angles , then sin^(2) alpha + sin^(2) beta =

Prove that if two angles alphaandbeta are complementary angles, then sin^(2)alpha+sin^(2)beta=1

If alpha , beta are supplementary angles , then cos^(2)alpha + sin^(2) beta =

If alpha and beta are complementary angles, then show that cot beta+cos beta= (cos beta)/(cos alpha) (1+sin beta) .

If alpha , beta are complementary angles , sin alpha = 3//5 , then sin alpha cos beta - cos alpha sin beta =

If alpha and beta are complementary angles to each other, the find the value of (1-sin^2 alpha)(1-cos^2 alpha)(1+cot^2 beta)(1+tan^2 beta)

If alpha,beta are complementary angles and sin alpha=(3)/(5), then sin alpha cos beta-cos alpha sin beta=

If alpha,beta are complementary angles, sin alpha=(4)/(5), then sin alpha cos beta+cos alpha sin beta=

If alpha,beta are complementary angles and sin alpha = (3)/(5) , then sin alpha cos beta - cos alpha sin beta =
