Question

What is the minimum value of cos θ, 0 ≤ θ ≤ 90°

Answer 1

Answer:

minimum value cos = 0 , ( 0 ≤ θ ≤ 90°)

Step-by-step explanation:

cos 90 = 0 ( 0 ≤ θ ≤ 90°)

Answer 2

Concept Introduction:-

It might resemble a word or a number representation of the quantity's arithmetic value.

Given Information:-

We have been given that $cos \theta, 0 \leq \theta \leq 90^{\circ}$

To Find:-

We have to find that $cos \theta, 0 \leq \theta \leq 90^{\circ}$

Solution:-

According to the problem

$cos \theta = 0$ when $\theta = 90^{\circ}, 270^{\circ}$

The Minimum value of $cos \theta$ is $-1$ when $\theta = 180^{\circ}$.

Final Answer:-

The correct answer is the Minimum value of $cos \theta$ is $-1$.
