To find the value of csc π using the unit circle:Rotate ‘r’ anticlockwise to form pi angle with the positive x-axis. The cosec of pi equals the reciprocal of the y-coordinate(0) of the point of intersection (-1, 0) of unit circle and r....
What is the exact value of cot(−90) and csc690 , using unit circle? https://socratic.org/questions/59ed2cfe11ef6b0b2cd1cba8 It depends on what you do want to use. Explanation: I assume that you actually mean to ask about cot(−90∘) (There is no nice way to express the...
In trigonometric functions, secθ represents the secant function, which is expressed as r/x, where r is the radius of the unit circle and x is the horizontal coordinate from the origin to point P. (2)余割函数cscθ与正弦函数sinθ互为倒数,即cscθ = 1/sinθ。 The co...
01:27on the unit circle. 01:29Let's say it's x, y. 01:32So t is a real number, 01:35and P(t) is on U. I'm going to describe it as follows. 01:42I'll have to break it up into cases. 01:45If t is bigger or equal to 0, ...
To find the cosecant of an angle without a calculator, you need to know the unit circle and the trigonometric ratios. First, identify the reference angle for the given angle. Then, determine the sine of the reference angle, and use the reciprocal of this value to find the cosecant of ...
The table below shows the sixteen special angles around the unit circle and their respective values for each function. Answer and Explanation: We're required to evaluate the exact value of the given trigonometric expressions, $$\begin{align} \cot 45^\circ \\[0.2cm] \csc 45...
For example, one may directly compute the arc length of the top half of the unit circle, given in Cartesian coordinates by the equation textstylex²+y²=1, as the integral: displaystylepi=int₋₁¹fracdxsqrt1-x². An integral such as this was proposed as a definition of π ...
Use the definition of cosecant to find the known sides of the unit circleright triangle. The quadrant determines the sign on each of the values.( (csc)(x)=((hypotenuse))((opposite)))Find the adjacent side of the unit circletriangle. Since the hypotenuse and opposite sides are known,...
