Question

good afternoon friends....... please give me the graph of cos(x) with neat explanation..... please don't copy from Google...​

Answer 1

Answer:

good afternoon frnd

Step-by-step explanation:

a right-triangle, cos is defined as the ratio of the length of the adjacent side to that of the longest side i.e. the hypotenuse. Suppose a triangle ABC is taken with AB as the hypotenuse and α as the angle between hypotenuse and base.

Cosine Function

Now, for this triangle,

cos α = Adjacent Side/Hypotenuse

Cosine Formula

From the definition of cos, it is now known that it is the adjacent side divided by the hypotenuse. Now, from the above diagram,

cos α = AC/AB

Or,

cos α = b/h
