What is the expansion of sin2x?
Continuing in this way, we eventually get that every even term is zero and hence vanishes from the Maclaren series, and every odd term has value (2⋅4n) . Therefore the Mclauen power series expansion for this function is : sin2x=∞∑n=02⋅4n(2n+1)!
What is sin series expansion?
In order to use Taylor’s formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin (x) = cos(x) sin (x) = − sin(x) sin (x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat.
What is the expansion of cos2x?
cos(2x)=1−(2x)22! +(2x)44!
What is expansion of Sinx?
The Maclaurin expansion of sinx is given by Sinx=x1!
How do you expand Sinx?
What is the formula for sine series?
an=2L∫L0f(t)cos(nπLt)dt. The series ∑∞n=1bnsin(nπLt) is called the sine series of f(t) and the series a02+∑∞n=1ancos(nπLt) is called the cosine series of f(t).
What is Sinx expansion?
In order to use Taylor’s formula to find the power series expansion of sin x we have to compute the derivatives of sin(x): sin (x) = cos(x) sin (x) = − sin(x) sin (x) = − cos(x) sin(4)(x) = sin(x). Since sin(4)(x) = sin(x), this pattern will repeat. sin(0) = 0 sin (0) = 1 sin (0) = 0 sin (0) = −1 sin(4)(0) = 0.

How are COs and sin expanded in a Maclaurin series?
Another approach could be to use a trigonometric identity. Consider this approach The functions cos ( u) and sin ( u) can be expanded in with a Maclaurin series, and cos ( c) and sin ( c) are constants.
