Question

Find the value (sin30+cos30)-(sin60+cos60) with steps

Answer 1

Question :

to fund the value of

(sin30+cos30)-(sin60+cos60)

Solution:

we know the value of

sin60=√3/2 = cos 30

sin30= cos 60 =1/2

then ,

(sin30+cos30)-(sin60+cos60)

$= ( \frac{1}{2} + \frac{ \sqrt{3} }{2} ) - ( \frac{ \sqrt{3} }{2} + \frac{1}{2} )$

$= \frac{1}{2} + \frac{ \sqrt{3} }{2} - \frac{1}{2} - \frac{ \sqrt{3} }{2}$

$= 0$
