Use an appropriate Taylor series to find the first four nonzero terms of an infinite series that is equal to sin(5/2).
koban [17]

Answer:

2.5, -2.61, 0.81, -0.12

Step-by-step explanation:

The taylor series of the function sin(x) around zero is given by

sin(x)=\sum_{n=0}^{\infty}\dfrac{(-1)^k}{(2k-1)!}x^{2k+1}=x-\dfrac{x^3}{3!}+\dfrac{x^5}{5!}-\dfrac{x^7}{7!}

Therefore,

\sin(\frac{5}{2})=\dfrac{5}{2}-\dfrac{[\frac{5}{2}]^3}{3!}+\dfrac{[\frac{5}{2}]^5}{5!}-\dfrac{[\frac{5}{2}]^7}{7!}+...

hence the first four nonzero terms of the series are

\dfrac{5}{2}=2.5\\\\-\dfrac{[\frac{5}{2}]^3}{3!} \approx -2.61\\\\\dfrac{[\frac{5}{2}]^5}{5!} \approx 0.81\\\\-\dfrac{[\frac{5}{2}]^7}{7!} \approx -0.12

Pleaseeee help!!!!! will give brainlist
Morgarella [4.7K]

For the equations, you could say numerous examples such as 3( 2h + (-3g) + 1). You could also do something like 3x1(2h + (-3g) + 1). Then draw an equilateral triangle by using a ruler and put 2h + (-3g) + 1 on one side. Then you could put 1 mark through each side of the triangle to show that they are all equal. When you simplify the Perimeter equation, you would get 6 h + -9g + 3 using the distributive property.
