    Mathematics: Post your doubts here!

    well if this is the question..answer is 11.25..do this way.. Sin(5a+θ)=Cos(θ-3a) or, Sin(5a+θ)=Sin{90+(θ-3a)} [ since, sin(90+B)=CosB ] Sine cancelled... or, 5a+θ=90+θ-3a or,8a=90 or,a=90/8 =11.25

    do this way..... Sin3x=-2Cos3x squaring both sides...Sin^2 (3x)=4Cos^2 (3x) add Cos^2 (3x) on both sides.. 1=5Cos^2 (3x)...now hope..u can solve it and get answers like...38.** , 98.** and....as u stated..!!

    Mathematics: Post your doubts here!

    I got the answer a=-3pi/16.......i think this is correct..this is how u do it.. Cos(5a+θ)=Sin(θ-3a) or,Cos(5a+θ)= -Cos(3pi/2 -θ+3a) [ since, Cos(270-angle)=-Sin(angle) ] Cos is cancelled...so.. or,5a+θ= -3pi/2 +θ -3a solving this..we get a=-3pi/16
