2016年10月17日 · Using the chain rule, we can treat #cos(3x)# as a variable and differentiate #cos^2(3x)# in relation to #cos(3x)#. Chain rule: #(dy)/(dx)=(dy)/(du)*(du)/(dx)# Let #u=cos(3x)# , then #(du)/(dx)=-3sin(3x)#

2015年5月5日 · The method of using integration by parts goes like this (I am changing $\cos(3x)$ to $\cos(x)$ for this example). $$\int \cos^2(x) dx = \cos(x)\sin(x) + \int \sin^2(x) dx$$ we used $u=\cos(x)$ and $dv = \cos(x)dx$.

x^2: x^{\msquare} \log_{\msquare} \sqrt{\square} \nthroot[\msquare]{\square} \le \ge \frac{\msquare}{\msquare} \cdot \div: x^{\circ} \pi \left(\square\right)^{'} \frac{d}{dx} …

2023年4月14日 · The formula of the integral of cos square (3x) contains the integral sign, coefficient of integration, and the function as cos. It is denoted by ∫{cos2 (3x)}dx. In mathematical form, the cos^2(3x) formula of integral is: $\int \cos^2(3x)dx =\frac{x}{2} +\frac{\sin(6x)}{12} + c$

What your instructor (hopefully) meant is that you need to use cos2(3x) = 21+cos(6x), which is a specialization of the trig identity cos2(x) = 21+cos(2x). Using ... What is ∫ cos2(4x)dx ? 161 sin(8x)+ 2x +C Explanation: In this instance we need to use a trig identity to re-express cos2(4x) ... How do you integrate ∫ cos3(3x)dx ?

Another trig chain rule derivative example, we differentiate cos^2 (3x), which requires two applications of the chain rule. We'll also fully simplify the deri...
