Sin 45= 1/√2 cos 30=√3/2 cos 45=1/√2 sin 30=1/2.put values in about form and you'll get your answer ^_^ thanks 1.4k views deepank prakash , lives in delhi answered 2 years ago We now find the sine of 36°, by first finding the cos of 36°.
⇒ Sin (75°) = Sin (30+45)° = Sin (30°)Cos (45°) + Sin (45°)Cos (30°) = ½ × 1/√2 + 1/√2 × (√3)/2 = 1/ (2√2) + (√3)/ (2√2)
The result can be shown in multiple forms. Notice that tan (75) can be written as sin(75)/cos(75) = sin(30 + 45) / cos(30 + 45) and using a couple of trig identities, we have. The exact value of cos(45°) cos ( 45 °) is √2 2 2 2.
