Differentiate implicitly on both sides with respect to x to get: 2=cos(y) • (dy/dx). Divide by cos(y) on both sides to get: dy/dx=2/cos(y). Use the trigonometric identity cos^2(y)+sin^2(y)=1 rearranged to...

to find dy/dx, multiply each item by the power of the x, and then decrease the power of the x by 1.Step 1 : 2x^2 -15x (multiplying by power of x)Step 2 : 2x^1 -15x^0Therefore:dy/dx = 2x ...
