This means after 360*2=720 degrees. Subtract this from 900 and you get 180 degrees. This means 900 degrees is actually just 180 degrees, only that it completes 2 circles. Cos900=cos (2π+π)=cosπ=-1. Sin(300) You can write this as Sin( 360 - 60) Here we know that Sine ( 360- x) is in fourth quadrant Sine is always positive in first and second quadrants But in fourth quadrand sine is negative So we get → -sin(60) We know the values ryt So from Exact values of sin(30), cos(30), tan(30), csc(30), sec(30), cot(30), Find exact values of all trigonometric functions when the angle is 30 degrees,blackpenr GCSE Maths revision tutorial video.For the full list of videos and more revision resources visit www.mathsgenie.co.uk.

+ ing a sense of availability of FRR from VSWTs rather than a specific value. However, a 300 MW load is also connected in parallel to this unit.

The result can be shown in multiple forms. Exact Form: 1 2 1 2. 300∘ has a reference angle of 60∘, since it is 60∘ away from the x -axis. Since cos(60∘) = 1 2, we know that cos(300∘) = 1 2 as well since cos(θ) > 0 in the fourth quadrant.

2019-02-27 · Cos is the opposite of sin. We should learn it like cos 0° = sin 90° = 1 cos 30° = sin 60° = √3/2 cos 45° = sin 45° = 1/√2 cos 60° = sin 30° = 1/2 cos 90° = sin 0° = 0 So, for cos, it will be like 1, √3/2, 1/√2, 1/2, 0 For tan We know that tan θ = sin θ /cos θ So, it will be

trig math 30. Find the exact value of cos 8 degrees cos 38 degrees + sin 8 degrees sin 38 degrees Find the exact value of cos 300 degrees. thanks guys cos 300 = 1/2 = 0.500 how do you know? I am supposed to show my work. You ought to know the rule on 30-60-90 triangles. If the hyp is 2, the shorter side is 1, and the longer side is sqrt3.

Originally, the Cos and Sin function has a period of π, or 360º. So if you add 360º (for degree) or π (for radian) to the angle value, you get the same value of the function. For example: Sin(30º)

If you draw the line x = 1/2 on the unit circle, you'll see that it intersects the circle twice; one point where the angle of the intersection point and the origin is 60 degrees (what we got) and one that is 300 degrees. Therefore the answer is t = 60* and t = 300*. I hope this helps! 2019-02-27 · Cos is the opposite of sin.
