The value of tan 90 degrees is undefined. The tangent of an angle is equal to the ratio of sine and cosine of the same angle. Learn how to derive the exact value of tan 90 at BYJU’S.
We develop methods for the solution of inhomogeneous Robin-type boundary value problems (BVPs) that arise for certain linear parabolic partial differential equations (PDEs) on a half-line, as well as a second-order generalization. We are able to obt
