If `A=130^@` and `x= sinA + cosA`, then

If A=125 and x=sinA^(@)+cosA^(@) then ………..

If x = 4cosA + 5sinA and y = 4 sinA - 5 cosA, then the value of x^2+y^2 is : यदि x = 4cosA + 5sinA तथा y = 4 sinA - 5 cosA है, तो x^2+y^2 का मान क्या होगा ?

If 3sinA +4cosA=4, " then find " 4sinA -3cosA .

If (2sinA)/(1+sinA+cosA)=k then (1+sinA-cosA)/(1+sinA)=

If (2sinA)/(1+sinA+cosA)=k then (1+sinA-cosA)/(1+sinA)=

If tan theta=(sinA-cosA )/(sinA+cosA) , then the value of sin A +cos A will be

If sinA+sin2A=x, cosA+cos2A=y then cosA=

If sinA+cosA=0 and A lies in 4th quadrant, find the values of sinA and cosA.

Fill in the gaps with correct answer . If (1+sinA)/(cosA) = sqrt2+1 , then the value of (1-sinA)/(cosA) is _____.
