WebbExample 1: When, sin X = 1/2 and cos Y = 3/4 then find cos(X+Y) Solution: We know cos(X + Y) = cos X cos Y – sin X sin Y. ... The ratio of sine and cosine is equal to the tangent of … WebbThe equation is solved using following steps: From y' + P (x)y = 0 you get d y y = − P ( x) d x, if y is not equal to 0 ∫ 1 y d y = − ∫ P ( x) d x log ( y ) = − ∫ P ( x) d x Or, y = e − ∫ P ( x) d x Therefore, y 1 = e − ∫ P ( x) d x y 2 = − e − ∫ P ( x) d x The expression indicates that it is necessary to find the integral: ∫ P ( x) d x
