Question

Evalvate Sin square 30 multiple cos square 45 + 4 tan square 30 + 1/2 sin square 90 + 1/8 cot square 60

Answer 1

Step-by-step explanation:

sin²30×cos²45+4tan²30+1/2sin²90+1/8cot²60

(1/2)²×(1/root2)²+4(1/root3)²+1/2(1)²+1/8(1/root3)²

$\frac{1}{4} \times \frac{1}{2} + \frac{4}{3} + \frac{1}{2} + \frac{1}{8} \times \frac{1}{3} \\ \frac{1}{8} + \frac{11}{6} + \frac{1}{24} \\ \frac{3}{24} + \frac{44}{24} + \frac{1}{24} \\ \frac{48}{24} = 2$
