Question

sin square 45 degree+cos square 60 degree + tan square 30 degree​

Answer 1

Answer:

The value of 2 tan² 45° + cos² 30° - sin² 60° is 2

Step-by-step explanation:

Given equation :

2 tan square 45 degree +cos square 30 degree- sin square 60 degree

The equation can be written as :

2 tan² 45° + cos² 30° - sin² 60°

Now we know,

tan 45° = 1

cos 30° =  

sin 60° =  

Substituting the values in the equation,

= 2 ( 1 ) ² + (  ) ² - (  ) ²  

= 2

Hence,

The value of 2 tan² 45° + cos² 30° - sin² 60° is 2
