# How Do You Find The Maximum Cosine Function?

## What is the maximum value of cosine?

Maximum value of cos θ is 1 when θ = 0˚, 360˚.

Minimum value of cos θ is –1 when θ = 180 ˚.

So, the range of values of cos θ is – 1 ≤ cos θ ≤ 1.

As the point P moves round the unit circle in either the clockwise or anticlockwise direction, the cosine curve above repeats itself for every interval of 360˚..

## How do you find the maximum value of a function?

The second way to determine the maximum value is using the equation y = ax2 + bx + c. If your equation is in the form ax2 + bx + c, you can find the maximum by using the equation: max = c – (b2 / 4a). The first step is to determine whether your equation gives a maximum or minimum.

## What is the formula for cosine?

In any right triangle, the cosine of an angle is the length of the adjacent side (A) divided by the length of the hypotenuse (H). In a formula, it is written simply as ‘cos’. Often remembered as “CAH” – meaning Cosine is Adjacent over Hypotenuse….Cosine (cos) function – Trigonometry.✔Formulae✔Other sides✔Hypotenuse1 more row

## Why is one the highest value of sine and cosine functions?

The value of Sin or Cos can never exceed 1, at least on the real number line. This is because the values of sin and cos include the Hypotenuse in there calculation, and they can never be greater than the hypotenuse (the hypotenuse is the longest side).
