Question

the value of (sin45°+cos 45°) is ?​

Answer 1

Step-by-step explanation:

the answer will be

(sin45+cos45)

=(1/root2+1/root2

=root2+root2/2

2root2/2

root2 is the answer of this OK friend

Answer 2

Answer:

Step-by-step explanation:

ANSWER:-

For attempting this question, we need to remember the values of Sin45 and Cos45.

$\boxed{\sf{Sin\ 45 = \frac{1}{\sqrt{2}}}}$

$\boxed{\bf{Cos\ 45 ={\frac{1}{\sqrt{2}}}}}$

Now, placing the values:-

We get:

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

$\implies \frac{2}{\sqrt{2}}$

So, $\huge{\boxed{\sqrt{2}}}$ is the simplified answer we get after cancelling 2 and root 2.

Some More identities:-

$sin^{2}\theta+cos^{2}\theta = 1$

$tan^{2}\theta+1=sec^{2}\theta$

$cot^{2}\theta+1=cosec^{2}\theta$

Complementary Angles:-

• These angles make to sum equal to 90 degree
• Some trigonometric Identities complementary are
• Sin and Cos
• Tan and Cot
• Sec and Cosec
• These all have an indivisible angle , theta $\boxed{\theta}$.
