Question

find the value of sin 90 - cos 60​

Answer 1

Answer:

1/2 please mark me as brainest

Answer 2

The value of sin90 - cos90 is $\frac{1}{2}$

Step-by-step explanation:

As we know that sin90 value is 1

Cos 60 value is 1/2

Trigonometry:

Trigonometry is the study of the relationship between the angles of a right-angle triangle and the lengths of the triangle's sides.

Sin 90 Formula

$sin 90 = \frac{Opposite side}{hypotenuse}$

We can calculate the sin 90 value from the unit circle.

Therefore sin 90 = 1

As we know that ,

$sinx=\frac{1}{cosx}$

$cos 60 = \frac{1}{2}$

we have to find sin90 - cos60,

Therefore,

sin90 - cos60= $1 - \frac{1}{2}$

⇒ $\frac{2-1}{2}$

⇒ $\frac{1}{2}$

Final answer:

The value of sin90 - cos 60  is $\frac{1}{2}$
