Question

the value of cot45/ sin30+cos60

Answer 1

Answer:

cot45 is 1

sin 30 is ½

and cos 60 is ½

so on putting respective values we get 1

Answer 2

Answer:

The value of cot45/ sin30+cos60 is 1.

Step-by-step explanation:

• In mathematics, the branch of trigonometry deals with specific functions of the specific angles and their applications related to the calculations.

• There are 6 types of functions in trigonometry. They are:

1) sine

2) cosine

3) tangent

4) cotangent

5) secant

6) cosec

• The angles in trigonometry is measured from $0^{o}$, $30^{o}$, $45^{o}$, $60^{o}$ and $90 ^{0}$degrees.

Given that:

$Cot$ $45^{0}$ / $sin 30^{0}$ + $cos 60^{0}$

To find:

The value of the expression given above =?

Solution:

$Cot 45^{0}$ / $sin 30^{0}$ + $cos 60^{0}$

1/ 1/2 + 1/2

= 1/ 1+1/2

=1

Therefore, the value of the expression is 1.
