Question

Find the value of Sin 90
- Cos 60​

Answer 1

Answer:

The required answer is $\frac{1}{2}$

Step-by-step explanation:

sin theta: The ratio of the opposite side's length to the hypotenuse's length is known as the right-angled triangle's sin theta.

Cos theta:  It is one of the acute angles and represents the ratio of the neighboring side to the hypotenuse.

Given: the expression is Sin $90$°- Cos $60$​°

To find: The value of the expression.

Solution:

According to question,

The value of Sin $90$° is 1.

And

The value of Cos $60$°​ is 1/2.

Now,

Sin $90$°- Cos $60$​°

⇒$1-\frac{1}{2}=\frac{1}{2}$

Therefore, the value of $\frac{1}{2}$.
