Is 3 Sinx the same as sin3x?

But leaving x nu03c0, sin3X can almost almost equal to 3Sinx, making (sinx)^3 0. As a cubic function has downward concavity and sinx has upward concavity. So the smaller x coordinates for sin^3 will give nearly zero value.

How do you write sin 3?

0.0523359. . .. Sin 3 degrees in radians is written as sin (3xb0 xd7 u03c0/180xb0), i.e., sin (u03c0/60) or sin (0.052359. . .).We can use trigonometric identities to represent sin 3xb0 as,

  • sin(180xb0 – 3xb0) sin 177xb0
  • -sin(180xb0 + 3xb0) -sin 183xb0
  • cos(90xb0 – 3xb0) cos 87xb0
  • -cos(90xb0 + 3xb0) -cos 93xb0

What is the period of Sinx sin2x?

The common period should be the least multiple of the 2 periods. The period of f(x) sin x is 2Pi, the period of f(x) sin 2x is Pi, then their common period is 2Pi.

How do you find the period of y sin 2x?

Explanation: The period of y(x) a sin (bx + c ) is #(2pi)/b. You see it here. y(x+u03c0)sin2(x+u03c0)sin(2x+2u03c0)sin2xy(x) .

What is the period of sin3x?

2π/3
We know that the period of sin x is 2π, therefore the period of sin3x is 2π/3. This implies the cycle of sin3x repeats itself after every 2π/3 radians.
