Answer:
0.44290869
Step-by-step explanation:
The Maclaurin series for sin⁻¹(x) is given by
sin⁻¹(x) = x +
Use the first five terms of the Maclaurin series above to approximate sin⁻¹ . (Round your answer to eight decimal places.)
Answer
sin⁻¹(x) = x +
in the above equation summation from n=1 to ∞
we are estimating this for the first 5 terms as follows
sin⁻¹(x) = x + + + +
sin⁻¹(x) = x + + + +
now to get
sin⁻¹() substitute
hence,
sin⁻¹() =
sin⁻¹() = 0.42857142 + 0.01311953 + 0.00108437 + 0.00011855 + 0.00001482
= 0.44290869
Nah that’s right a is the correct answer
Answer:
80%
Step-by-step explanation:
1. Formula for collecting efficiency is:
(Output energy÷Input energy) x 100
2. Plug in the values:
(40J÷50J)x 100
= 80%
The cosine ratio is the side adjacent to the reference angle over the hypotenuse. Angle T has a side opposite of length 68, and the hypotenuse is 85. Therefore, the cosine of T is 68/85. That gives us a decimal of .8. It's very important that the ratio of sin and cos are decimals less than 1 but greater than 0. If you try to take the inverse cosine of, say, 1.4 on your calculator you will get an error message. That's because sin and cos oscillate between 1 and -1 on the graph and do not exist higher or lower than that.
