Question

Find the value of sin 30 into cos 60 + cos 30 into sin 60 is equal to sin 90 or cos 90

Answer 1

Answer:

Step-by-step explanation:

Sin30×Cos 60 + Sin60×Cos30

1/2×1/2 + root3/2×root3/2

1/4 + 3/4

4/4

1

Sin90 = 1

Therefore, Sin30×Cos 60 + Sin60×Cos30 = Sin 90

Answer 2

$sin3 {0}^{0} cos6 {0}^{0} + \cos3 {0}^{0} \: \sin6 {0}^{0}$

$\frac{1}{2} \times \frac{1}{2} \: + \frac{ \sqrt{3} }{2} \times \frac{ \sqrt{3} }{2}$

$= \frac{1}{4} + \frac{3}{4}$

$= \frac{4}{4} = 1$

here the answer comes

$1$
