对于复变的指数函数,我们在0.2讲中已经讨论了Euler公式: e^{i\theta}=\cos \theta + i\sin \theta ,据此,我们可以定义: 定义2:(复变指数函数)对于复数 z=x+iy \quad(x,y\in \mathbb{R}) ,我们定义指数函数 e^z=e^{x+iy}:=e^x\cdot e^{iy}=e^x (\cos y + i\sin y) 由于我们发现...
Find the length of the curve r = 6(1 + \cos \theta) }]. Find the length of the curve y = 2x^(3/2) from x = 0 to x = 5/4. Find the length of the curve y=\frac{3}{4}x^\frac{4}{3}-\frac{3}{8}x^\frac{2}{3}+9 for 1\geq x \geq 8. ...
e^{\hat{\omega}\theta} = I+\hat{\omega}\sin\theta+\hat{\omega}^2(1-\cos\theta) 当纯平移时,有 e^{\hat{\xi}\theta} = \begin{bmatrix}I&\theta v\\0&1 \end{bmatrix} 式子中的各个指数为 e^{\hat{\xi}_1\theta_1} = \begin{bmatrix}\cos\theta_1&-\sin\theta_1&0&0\...
Answer to: Find the exact value of sin theta and tan theta when cos theta has the indicated value. cos theta = 1 By signing up, you'll get...
$$\begin{align} \cos^2\theta+\sin^2\theta&=1\\ \csc\theta&=\dfrac{1}{\sin\theta}\\ \end{align} $$ Answer and Explanation:1 We are given an equality, and we want to prove that it is a trigonometric identity. Adding the fractions in the left side, si...
RT.我记得有一个cos(theta1) = cos(theta2) * cos(theta3)的公式,请分别解释一下theta1,2,3之间的关系,以及该公式的正式名称叫什么?请不要乱Copy, 相关知识点: 试题来源: 解析 你写的这个公式是正确的空间中有过O的三条直线OA,OB,OC.OA与OB的夹角设为x1,OC与OB的夹角设为x2.OA与OC的夹角设为x3...
Verify the identity 1/tan(theta)csc(theta) = cos(theta).My old trig teacher said to draw a vertical bar through the =; then nothing goes over the bar. You are NOT working with an equation. The idea is to use identities to transform a side into something ever closer to the other sid...
Answer to: If sin theta is greater than 0 and tan theta = -1/2, find the exact value of cos theta. By signing up, you'll get thousands of...
