Web7 years ago. You have to know that sin (30 degrees) = sin (pi/6) is 1/2. This is the only trig function you have to memorize. Then, from the Pythagorean theorem, cos (30) is rt (3)/2. You can figure out sin (45) (see this video). From these you can get all the 12 simplest angles on the unit circle (8 multiples of 30 deg, 4 multiples of 45 (plus ... WebTo find the value of cos π/4 using the unit circle: Rotate ‘r’ anticlockwise to form pi/4 angle with the positive x-axis. The cos of pi/4 equals the x-coordinate (0.7071) of the point of …

"WebThe degrees cancel out. So you have a 45 over 180. This goes four times. So this is equal to-- you have the minus sign-- minus pi over 4 radians. So the arctangent of minus 1 is equal to minus pi over 4 or the inverse tangent of minus 1 is also equal to minus pi over 4. Now you could say, look. If I'm at minus pi over 4, that's there. That's fine. " - Csc of pi over 4

WebFeb 21, 2024 · So, to check whether the angles α and β are coterminal, check if they agree with a coterminal angles formula: a) For angles measured in degrees: \beta=\alpha\pm (360\degree\times k) β = α ± (360° × k) where k k is a positive integer. b) For angles measured in radians: \beta = \alpha \pm (2\pi\times k) β = α ± (2π × k) here k is a ... WebFor every trigonometry function such as csc, there is an inverse function that works in reverse. These inverse functions have the same name but with 'arc' in front. So the inverse of csc is arccsc etc. When we see "arccsc A", we interpret it as "the angle whose cosecant is A". csc 30 = 2.000 ...
