Find the derivative of sin2X<br>​
inn [45]

Step-by-step explanation:

Derivation using Product rule : -

To find the derivative of f(x) = sin 2x by the product rule, we have to express sin 2x as the product of two functions. Using the double angle formula of sin, sin 2x = 2 sin x cos x. Let us assume that u = 2 sin x and v = cos x. Then u' = 2 cos x and v' = -sin x. By product rule,

f '(x) = uv' + vu'

= (2 sin x) (- sin x) + (cos x) (2 cos x)

= 2 (cos2x - sin2x)

= 2 cos 2x

This is because, by the double angle formula of cos, cos 2x = cos2x - sin2x.

Thus, derivation of sin 2x has been found by using the product rule.

A​ state's recidivism rate is ​22%. This means about ​22% of released prisoners end up back in prison​ (within three​ years). Su
storchak [24]

The probability that both of them go back to prison is 4.48%.

<h3>What is probability?</h3>
  • Probability is a measure of the likelihood of an event occurring.
  • Many events cannot be predicted with total certainty.
  • We can predict only the chance of an event to occur i.e., how likely they are going to happen, using it.
  • The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates the impossibility of the event and 1 indicates certainty.

The state recidivism rate is given by 22%.

So, the probability that both of the prisoners will go back to prison will be:

  • = 22% × 22%
  • = 0.22 × 0.22
  • = 4.84%

Hence, the probability that both of them go back to prison is 4.48%.
