Question

Write the value of sin2 30+ cos2 60

Answer 1

Answer:

Your answer is 61.01

Answer 2

$\huge\bold\star\purple{SOLUTION : }$

➡ sin² 30° + cos² 60°

• sin 30° = 1/2
• cos 60° = 1/2

$⟹ { (\frac{1}{2}) }^{2} + {( \frac{1}{2}) }^{2}$

$⟹ \frac{1}{4} + \frac{1}{4}$

$⟹ \frac{1 + 1}{4}$

$⟹ \frac{2}{4}$

$⟹ \frac{1}{2}$

$\boxed{∴ sin² \: 30° + cos² \: 60° = \frac{1}{2} }$
