Find (dy)/(dx) in the following: 1.2x+3y=sin x2.2x+3y=sin y3.ax+by^(2)=cos y

Find (dy)/(dx) in the following: 1.2x+3y=sin x2.2x+3y=sin y3.ax+by^(2)=cos y

If sin x + cos y = (1) / (3) and cos x + sin y = (3) / (4) then tan ((xy) / (2)) =

Consider the system of equations x cos^(3) y+3x cos y sin^(2) y=14 x sin^(3) y+3x cos^(2) y sin y=13 The value of sin^(2) y+2 cos^(2) y is

Consider the system of equations x cos ^(3) y + 3 x cosy sin^(2) y = 14 t o (1) and x sin^(3) y + 3 x cos^(2) y sin y = 13 to (2) The value of sin^(2) y + 2 cos^(2) y is

If x = 4 cos A + 5 sin A and y = 4 sin A - 5 cos A, then the value of x^(2) + y^(2) is:
