Question

Find the value of cos0 +sin 90+ root 2 sin 45​

Answer 1

Answer:

3

Step-by-step explanation:

we know ,

cos 0 = 1,

sin 90 = 1,

sin 45 = 1/ root 2,

therefore,

cos 0 + sin 90 + root 2 × sin 45...(given)

therefore,

=1 + 1 + root 2 × 1/ root 2

=2 + 1

=3

Answer 2

Given : cos0° + sin90° + √2 sin45°

To find : The answer to the given addition.

Solution :

We can simply solve this mathematical problem by using the following mathematical process. (our goal is to calculate the answer to the given addition)

First of all, we will be determining the values of the individual addends.

So, the values are :

• cos0° = 1
• sin90° = 1
• sin45° = $\frac{1}{ \sqrt{2} }$

So, the final value will be :

= cos0° + sin90° + √2 sin45°

= 1 + 1 + (√2× $\frac{1}{ \sqrt{2} }$ )

= 1 + 1 + 1

= 3

(This will be considered as the final result of the given mathematical problem.)

Hence, the value of cos0° + sin90° + √2 sin45° is 3
