Question

Sin^2 pie/30 + sin^2 pie/4 + sin^2 Pie/6

Answer 1

Answer:

sin²180/3+ sin²180/4 + sin²180/6

sin² 60+ sin²45 + sin²30

(√3/2)²+(1/√2)²+(1/2)²

3/4+1/2+1/4

6/4

3/2

Answer 2

Answer:

sin^2π/3 + sin^2π/4 + sin^2π/6

Step-by-step explanation:

= (sinπ/3)^2 + (sinπ/4)^2 + (sinπ/6)^2

= (√3/2)^2 + (1/√2)^2 + (1/2)^2

= 3/4 + 1/2 + 1/4

= 3/4 + 2/4 + 1/4

= 6/4 = 3/2 ( or ) 1.5
