## KTU S2 Vector Calculus, Differential Equations and Transforms | MAT 102 | Notes (2019 Scheme)

Vector Calculus, Differential Equations and Transforms MAT 102 of first-year KTU is the maths subject that help's you to calculate derivatives and line coordinates of vector functions and surface and shape coordinates to find their applications and their correlations and applications. Solve equations of homogeneous and homogeneous linear equations with constant coefficients and calculate Laplace transform and use them to solve problems derived from engineering.
