If a is 30 than find sin 3a =3 sin a - 4 sin raise to power 3. A?
Most Upvoted Answer
If a is 30 than find sin 3a =3 sin a - 4 sin raise to power 3. A?
Given Information:
a = 30
Calculation of sin 3a:
To find sin 3a, we can use the trigonometric identity: sin 3a = 3 sin a - 4 sin^3 a
Substitute the value of a:
sin 3(30) = 3sin(30) - 4sin^3(30)
sin 90 = 3(sin 30) - 4(sin^3 30)
Calculating sin 90:
sin 90 = 1
Calculating sin 30:
sin 30 = 1/2
Applying the values:
1 = 3(1/2) - 4(sin^3 30)
1 = 3/2 - 4(sin^3 30)
Solving for sin^3 30:
1 = 3/2 - 4(sin^3 30)
1 = 3/2 - 4(sin^3 30)
1/2 = -4(sin^3 30)
-1/8 = sin^3 30
Calculating sin 30:
sin 30 = 1/2
Therefore, the value of sin 3a is:
sin 90 = 1
Conclusion:
The value of sin 3a when a is 30 is equal to 1.
