Q. Solve the equation.dxdy=sin(y)cos(x)Choose 1 answer:(A) y=arcsin(−sin(x))+C(B) y=arcsin(−sin(x)+C)(C) y=arccos(−sin(x))+C(D) y=arccos(−sin(x)+C)
Rewrite equation: We rewrite the equation as sin(y)dy=cos(x)dx. Now we can integrate both sides: ∫sin(y)dy=∫cos(x)dx.
Integrate both sides: The integral of sin(y)dy is −cos(y), and the integral of cos(x)dx is sin(x). So we have −cos(y)=sin(x)+C, where C is the constant of integration. To solve for y, we take the arccosine of both sides: y=arccos(−sin(x)+C). However, since the range of arccos is [0,π], and the range of arcsin is [−π/2,π/2], we should use arcsin to get the general solution. Therefore, we rewrite the equation as −cos(y)0.
