Question

solve sin45+cos45.solve it first to get more points
​

Answer 1

Answer:

sin 45° + cos 45°

= 1/√2 + 1/√2

=2/√2

= √2

Answer 2

Step-by-step explanation:

$\sin(45) + \cos(45) \\ = > \frac{1}{ \sqrt{2} } + \frac{1}{ \sqrt{2} } \\ = > \frac{1 + 1}{ \sqrt{2} } \\ = > \frac{2}{ \sqrt{2} } \\ = > \frac{ \sqrt{2 } \times \sqrt{2} }{ \sqrt{2} } \\ = > \sqrt{2}$
