If y=y(x) is the solution of the differential equation dydx=(tanx−y) – InterviewSolution

1.	If y=y(x) is the solution of the differential equation dydx=(tanx−y)sec2x, x∈(−π2,π2), such that y(0)=0, then y(−π4) is equal to :
Answer» If $y = y (x)$ is the solution of the differential equation $\frac{d y}{d x} = (tan x - y) {sec}^{2} x,$ $x \in (- \frac{π}{2}, \frac{π}{2}),$ such that $y (0) = 0,$ then $y (- \frac{π}{4})$ is equal to :
