Question

find the value of sin square theta+cos square theta+1​

Answer 1

Answer:

First, let's recall the Pythagorean identity and the two other forms of it. Cosine squared plus sine squared equals 1 can also be written cosine squared theta equals 1 minus sine squared theta or sine squared theta equals 1 minus cosine squared theta.

Answer 2

sin² θ + cos² θ + 1 = 2

Given :

The expression sin² θ + cos² θ + 1

To find :

The value of the expression

Formula :

sin² θ + cos² θ = 1

Solution :

Step 1 of 2 :

Write down the given expression

The given expression is sin² θ + cos² θ + 1

Step 2 of 2 :

Find the value of the expression

We are aware of the Trigonometric identity that

sin² θ + cos² θ = 1

Thus we get

The given expression

= sin² θ + cos² θ + 1

= 1 + 1

= 2
