NettetThe theory says if you integrate sine or cosine over a single full period (0 to 2pi) that the answer is 0. You also get zero for any integer number of full periods. For example, if … NettetApr 11,2024 - The number of integral values of a for which the equation cos 2x + a sin x = 2a – 7 possesses possible solutions isa)2b)3c)4d)5Correct answer is option 'D'.

Mathematically, this is written as ∫ cos x dx = sin x + C, where, C is the integration constant. Here, '∫' is a symbol of integration and it is known as the "integral" cos x is the integrand dx means the integration is with respect to x. But how to do the integration of cos x? green man emblems hobby lobby
