Enter a problem... The exact value of sec(0) sec (0) is 1 1. One to any power is one. Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor.

x^{2}-x-6=0 -x+3\gt 2x+1 ; line\:(1,\:2),\:(3,\:1) f(x)=x^3 ; prove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) \frac{d}{dx}(\frac{3x+9}{2-x}) (\sin^2(\theta))' \sin(120)

Mar 18, 2015 · If you want to get $\sec^2(0)$, you should first notice that $\sec^2(0)=\dfrac1{\cos^2(0)}$. I would, then, first get $\cos(0)$, and then press the x^2 and 1/x buttons. (Or, on a graphing calculator, I would just type in 1/cos(0)^2 or something similar.

sec²x与tan²x的关系如下：tan²x=sec²x/sin²xtanx的导数为sec²xsecx的导数为tanxsecxtan²x=sin²x/cos²xsec²x=1&

Dec 22, 2017 · sec的平方0等于1。 分析过程如下：sec²0=1/cos²0，又因为cos0=1，由此可得：sec²0=1。 余弦（余弦函数），三角函数的一种。

sec(0) sec ( 0) 的准确值为 1 1 。 一的任意次幂都为一。 免费的数学问题解答者采用逐步解题讲解方式回答您的代数、几何、三角集合学、微积分以及统计学家庭作业问题，就像一位数学辅导老师那样为您提供帮助。

sec 0等于多少sec0=1。以下是解题步骤：因为sec=1/cos。所以sec0＝1/cos0=1。 扩展资料三角函数关系：1、倒数关系：si
