If `|[asintheta,-bcostheta],[acostheta,bsintheta]|=12` and `a+b=7`, `agtb`, then a & b are:

If asintheta+bcostheta=c , find acostheta-bsintheta=?

If asintheta+bcostheta=c , then acostheta-b sintheta is equal to

If x=asintheta-bcostheta,y=acostheta+bsintheta , then which of the following is true ?

If (a costheta_1,asintheta_1),(acostheta_2,a sintheta_2) , and (acostheta_3a sintheta_3) represent the vertces of an equilateral triangle inscribed in a circle. Then.

If ((asintheta-bcostheta)/(asintheta+bcostheta))=((a^2-b^2)/(a^2+b^2))^k and tan theta=a/b then k=

Evaluate (a+bcostheta)^2+(bsintheta)^2

If x=acostheta , y=bsintheta then eliminate theta .

If x/acostheta+y/bsintheta=1,x/asintheta-y/bcostheta=1 , then eliminate theta .

If x=acostheta+bsinthetaandy=bcostheta-asintheta ,then x^(2)+y^(2) is equal to

If DeltaABC having vertices A (acostheta_1, asintheta_1), B (acostheta_2, asintheta_2), and C (acostheta_3, asintheta_3) are equilateral triangle, then prove that cos theta_1 + costheta_2 + cos theta_3 = 0 and sintheta_1 + sintheta33
