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

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 =

(A) sin^(2)5+sin^(2)10+......+sin^(2)85=(17)/(2) (R) : If alpha+ beta=90^(@) then sin^(2)alpha+ sin ^(2) beta=1

sin(90^circ+2theta) is

If A+B+C=90^(@) then sin^(2)A+sin^(2)B+sin^(2)C=

If alpha+beta=90^@ and alpha=2beta , then cos^2alpha+sin^2beta = …………………
