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. what does that have to do with cos300? Cos(x) = Cos(-x) (1) Cos(x + 360) = cos(x) (2) Cos(300) = (using (2)) cos(-60) = (using (1)) cos(60) = using what

It's easiest to see in terms of the circle definitions of sines and cosines. If you draw a line of length 1 at 60 degrees above the x-axis, the x-component is cos(60 ). If

The value of cos of angle $30$ degrees is equal to $\dfrac{\sqrt{3}}{2}$ in fraction form exactly. It is an irrational number and equals to $0.8660254037\ldots$ in decimal form and the same value is considered as $0.866$ approximately in mathematics.

To find cos of another number, please enter the number below and press "Calculate Cos". Thus, $\sin 300\degree$ is negative, $\cos 300\degree$ is positive, and $\tan 300\degree$ is negative. Checkpoint 4.6 . For angles in each of the four quadrants shown below, explain why the indicated trig ratios are positive.

In grammar, degree refers to one of the three forms used in the comparison of adjectives and adverbs: positive, comparative, and superlative. porcorex/Getty Images The word "degree" is from the Latin de- (down) + gradus (a step). In English

Select degrees or radians in the drop down box and calculate the exact cos 300° value easily. α. Imagine the unit circle: We know that 300∘ is in the fourth quadrant, where cosine is positive. 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.

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.
