the X and Y coordinates of 90 degrees on the unit circle are X = 0 and Y = 1 So the adjacent side = 0 and the opposite side = hypotenuse = 1 so sine 90 degrees = 1/1= 1 cos 90 degrees = 0/1 = 0 tan 90 degrees = 1/0 = infinity At 180 degrees...

It is not the sec, it's the inverse sec, right? So, x/3 is the angle, and that means (since sec is hypotenuse/adjacent), that you need to make a triangle in standard position having x as the hyp and 3 as the adj side. Use Pythagoras to find...

If the tangent of an angle is √2/x then the cotangent is the reciprocal x/√2. Now rationalize it by multiplying top and bottom by √2 and you get x√2/2 The angle whose cosine is 4/5 must be a 3-4-5 right triangle. So draw it and read off the...

First, let's break down the terminology to understand what it means. You might recall that the regular inverse sine, cosine, or tangent of a number--let's say 0.5--yields a new number x such that the sine, cosine, or tangent of x is equal t...
