The secant of an angle, α, defined with reference to a right angled triangle is sec(α)=1cos(α)=hypotenuseadjacent side=hb . The secant of a complex argument, α, is sec(α)=2eiα+e−iα . Tips In floating-point arithmetic,secis a bounded function. That is,secdoes not re...
How do you prove sec(x) - sin(x) tan(x) = cos(x)? Verify the following: tan(x) \: csc(x) = sec(x). What is sin(x) - csc(x) simplified? How do you simplify 1 + tan(x - 1) - tan(x)? When does x equal if sec(x) = 3?
How would you approximate the angle between \overrightarrow u = (3,-7) and \overrightarrow v = (2,2) in degrees? Find a. b. |a| = 3, b = sqrt(6), the angle between a and b is 45 degrees. Find a . b. |a| = 7, |b| = 8, the angle between a and b is 30 degre...

使用商数恒等式以正弦和余弦书写 cot(x)cot(x)。 −cos(x)sin(x)-cos(x)sin(x)因为两边已证明为相等,所以方程为恒等式。 csc(−x)sec(−x)=−cot(x)csc(-x)sec(-x)=-cot(x) 是一个恒等式csc(−x)sec(−x)=−cot(x)csc(-x)sec(-x)=-cot(x) ([ )] | √...
As we see, a trigonometric identity is an equivalence between two or more trigonometric functions. These are used to simplify mathematical calculations. Answer and Explanation: {eq}\begin{align*} \sec \left(x\right)+\tan \left(x\right)&=\frac{1}{\sec \left(x\right)-\tan \l...

When verifying trigonometric identities, we usually need to show that the left-hand side of an equation is equal to the right-hand side. To do this, we can use trig definitions (such as tanx=sinxcosx) and known trig identities (such as cos2x...
