" 4.If "sin A+sin^(2)A=1" then the value of the expression "cos^(2)A+cos^(4)A" ."

If sin A + sin^2 A = 1 , then the value of the expression (cos^2A+ cos^4 A) is

If sin A+sin^(2)A=1, then the value of cos^(2)A+cos^(4)A is 2(b)1(c)-2(d)0

If sinA+sin^2A=1, then the value of cos^2A+cos^4A is

Find the value of the expression sin[cot^(-1){cos (pi/2)}]

find the value of expression (sin2x)/(1+cos2x) is:

then value of the expression sin^(-1)(cos(cos^(-1)(cos x)+sin^(-1)(sin x)))

If sin A+sin^(2)A+sin^(3)A=1, then find the value of cos^(6)A-4cos^(4)A+8cos^(2)A

If sin A + sin^2 A = 1 , then the value of cos^2A + cos^4 A is यदि sin A + sin^2 A = 1 , तो cos^2A + cos^4 A का मान है-

If A = 5^(@) then the value of expression (( secA)/((1 - 4sin^(2)A)) + (cosec A)/((4 cos^(2)A -1)))^(2) is :
