It would be nice if you guys have given explanation for this question ​

Answer 1

HOPE THIS HELPS YOU MATE AND PLEASE MARK ME AS BRAINLY ❤❤

Answer 2

Answer:

Concept: the question can be solved by placing the values of trigonometry given.

Given: Sin 60° + Cos 0° - Tan 45° + Cot 45° - Sin 90°

To find: the answer of the above .

Step-by-step explanation:

in the trigonometry  values are given for 30°,45°,60°,90° of sin , cos ,tan, cot  and many others.

so, the values are sin 60° = $\frac{\sqrt{3} }{2}$

cos 0°     =  1.

tan 45° = 1.

cot 45°   = 1.

sin 90° =   1.

so, if we place the above values in the format given in the question , we will get

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

so, the answer is $\frac{\sqrt{3} }{2}$.
