Solve for `x,y: sinxcosy=1/4 , 3tanx=tany` then sin(x−y)=

If y=(tanx)/(tan3x), then

If cosx=tany,cosy=tanz and cosz=tanx , then sin^2x=?

Find dy/dx if 3x^5-y=tany

Solve (dx )/(dy) +x/y= sin y

Solve: dy/dx = sin(x+y) + cos(x+y)

Solve: dy/dx = sin(x+y) + cos(x+y)

Find dy/dx if 3x-4y=tanx

If cos x=tany, cos y=tanz and cos z = tanx , then sinx = 2sin theta where theta is (where, x,y, z, theta are acuate angles)

Solve the equation for x and y , |sin x + cos x|^( sin^(2) x-1//4)=1+|siny| and cos^(2)y=1+sin^(2)y .

Solve x-y+z=4 , x+y+z=2 , 2x+y-3z=0
