If `sinx/siny=1/2` and `cosx/cosy=3/2` then `sqrt(8+sec^2y)=`

If sinx+siny=1/2 and cosx+cosy=1 , then tan(x+y)=

If sinx + siny = 1/2 and cosx + cosy =1 , then tan(x + y)=.......

If sinx+siny=p,cosx+cosy=q then sec(x+y)=

If sinx-siny=a and cosx+cosy=b,prove that tan((x+y)/2)=+-sqrt((4-a^2-b^2)/(a^2+b^2))

If (sinx)/(siny)=(1)/(2),(cosx)/(cosy)=(3)/(2) , where x,y in (0,(pi)/(2)) , then the value of tan (x+y) is equal to

If sinx+cosy=(1)/(3) and cos x+siny=(3)/(4) , then the value of tan((x-y)/(2)) is equal to

If (sinx)/(siny)=1/2,(cosx)/(cosy)=3/2 , where x , y , in (0,pi/2), then the value of "tan"(x+y) is equal to (a) sqrt(13) (b) sqrt(14) (c) sqrt(17) (d) sqrt(15)

If (sinx)/(siny)=1/2,(cosx)/(cosy)=3/2 , where x , y , in (0,pi/2), then the value of "tan"(x+y) is equal to (a) sqrt(13) (b) sqrt(14) (c) sqrt(17) (d) sqrt(15)

If (sinx)/(siny)=1/2,(cosx)/(cosy)=3/2 , where x , y , in (0,pi/2), then the value of "tan"(x+y) is equal to (a) sqrt(13) (b) sqrt(14) (c) sqrt(17) (d) sqrt(15)
