(cos0^(@)+sin90^(@))xx(tan30^(@)xxtan60^(@)) is:

What is the value of {(([4 cos (90-A)sin^3(90+A)]-),([4 sin(90+A) cos^3(90-A)]))} /(cos ((180+8A)/2)) ?

((cos (90 ^ (@)) - theta) sin (90 ^ (@) - theta)) / (tan (90 ^ (@) - theta))

What is the value of ({[[4cos (90-A)sin^3 (90+A)]-], [[4sin(90+A)cos^3(90-A)]]})/(cos((180+8A)/(2))) ?

Prove that (i) sin (90^(2)-A)cos (90^(@)-A)=(tanA)/(1+tan^(2)A) (ii) (cos(90^(@)-A).cosA)/(cotA)-sin^(2)A=0

Prove that : (i) sinthetacos(90^(@)-theta)+sin(90^(@)-theta)costheta=1 (ii) sectheta" cosec"(90^(@)-theta)-tanthetacot(90^(@)-theta)=1 (iii) (sintheta*sec(90^(@)-theta)cot(90^(@)-theta))/("cosec"(90^(@)-theta)*costheta*tantheta)-(tan(90^(@)-theta))/(cottheta)=0 (iv) (1+sin(90^(@)-theta))/(cos(90^(@)-0))+(cos(90^(@)-theta))/(1+sin(90^(@)-0))=2"cosec"theta
