2015年3月18日 · To calculate $\sec^2{x}$ on a graphing calculator, you should have the ability to write strings of functions with parenthesis and the like and can write it as:

Prove the following trigonometric identity: $$1 + \\tan^2\\theta = \\sec^2\\theta$$ I'm curious to know of the different ways of proving this depending on different characterizations of tangent …

2013年9月21日 · Yes, this can be done, but the method is far longer than if you know the derivative of $\tan x$ already. The point is to convert this trigonometric integral into the integral …

2020年6月7日 · If you know the identity $\sec^2x=1+\tan^2x$, then this easily simplifies to: $$\sec^2 x-\tan^2 x$$ $$=(1+\tan^2x)-\tan^2x$$ $$=1$$ But in your question you mentioned …

2018年11月23日 · Here is a detailed solution. Move on! $$\require{cancel} \begin{align} \frac{\sec^2\theta-\cos^2\theta}{\tan^2\theta}&=\frac{\frac{1}{\cos^2\theta}-\cos^2\theta ...

2021年6月14日 · It seems that what we are asked to notice is that $$ \sec^2 x \ + \ \csc^2 x \ \ = \ \ \frac{1}{\cos^2 x} \ + \ \frac{1}{\sin^2 x} \ \ = \ \ \frac{\sin^2 x \ + \ \cos ...

2025年1月12日 · Tan^x and sec^x are both positive and symmetric to x=(2n-1)π/2. The functions are different by 1 for all x. At x and x+£x the values of both functions differ by

A truck travels along a straight, level road at the speed of 99ft/sec. when the driver is forced to apply the breaks to avoid an accident. If the truck undergoes a constant deceleration of …
