Question

Find out the value of cos^2(35) + tan^2(45) + sin^2(35)

Answer 1

Answer:

2

Step-by-step explanation:

Cos^² (35) + sin^2 (35) + tan ^2 (45)

= 1 + tan²45 = 1+1 =2

Answer 2

Using relation,


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

We have,


${ \cos}^{2} 35 + { \tan}^{2} 45 + { \sin}^{2} 35 \\ \\ = 1 + { \tan }^{2} 45 \\ \\ = 1 + 1 = 2$
