This type of integral would typically be found in a Calculus 1 class. Normally I would expect a == b to be a logical expression which is either True or False. Any explanation for the strange behaviour discovered by accident? Dec 13, 2015 ... Mathematica automatically simplifies the Sin[x]/Cos[x] after ReplaceAll (/.). Defer is a useful function for preventing that. Detailed step by step solution for integral of cos(x)cos(nx) Derivatives of sin(x) and cos(x) · FUN‑3 (EU) · FUN‑3.A (LO) · FUN‑3.A.4 (EK) ... 'PHOTOGRAPHY IS THE ARTISTIC LENS THROUGH WHICH I EXPRESS NATURE'S BEAUTY, WHILE TECHNOLOGY ALLOWS ME TO PUSH ITS BOUNDARIES.' - PHOTOGRAPHER, CHRIS PERANI. Jul 21, 2023 ... The x 2 is the outer and cos(x) is the inner. This is because cos(x) replaces the x in x 2. What I meant by the other way around was if cos(x) was the outside ... Ex 7.2, 34 Integrate √(tan⁡x )/sin⁡〖x cos⁡x 〗 Simplifying the function √(tan⁡x )/sin⁡〖x cos⁡x 〗 = √(tan⁡x )/(sin⁡〖x cos⁡x 〗. cos⁡x/cos⁡x ) = √(tan⁡x ) ...
