`SinA - CosA = 0 , Sin^4A + Cos^4A = ?`

Show that : Sin^4A - Cos^4A = ( SinA + CosA ) ( SinA - CosA )

Find simplified form : ( SinA + CosA )^2 + ( SinA + CosA )^2 =

Show : (( Sin^3A + Cos^3A ) /( SinA + CosA ) ) = 1 - SinACosA

Prove that: (sinA - 2sin^(3)A)/(2 cos^(3)A - cosA) = tan A

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 A lies in the first quadrant and 6tanA = 5, then the value (8 sinA -4 cosA)/(cosA + 2 sinA) is : यदि A प्रथम चतुर्थाश में स्थित है तथा 6tanA = 5 है, तो (8 sinA -4 cosA)/(cosA + 2 sinA) का मान क्या होगा ?

Evaluate : CosA - SinA = 1 ,then find the value of CosA + SinA

Evaluate : CosA - SinA = 1 ,then find the value of CosA + SinA

If |[cos(A+B), -sin(A+B), cos2B], [sinA, cosA, sinB], [-cosA, sinA, cosB]|=0 , then B=

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