Question

find the value of sin90° -cos 60°​

Answer 1

Answer:

sin90 - cos 60 = 1-1/2=1/2

hence answer is 1/2

Answer 2

Step-by-step explanation:

Using the standard trigonometric values,

$\sin90 ^\circ = 1 \\ \cos60 ^\circ = \frac{1}{2}$

According to the question,

$sin90° -cos 60°$

$1 - \frac{1}{2}$

$\frac{2 - 1}{2}$

$\frac{1}{2}$

Hence the value is $\frac{1}{2}$
