Question
Differentiate the following functions with respect to x:
$\sin(2\sin^{-1}\text{x})$

Answer

Let, $\text{y}=\sin(2\sin^{-1}\text{x})$
Differentiate it with respect to x,
$\frac{\text{dy}}{\text{dx}}=\frac{\text{d}}{\text{dx}}\Big(\sin(2\sin^{-1}\text{x})\Big)$
$=\cos\big(2\sin^{-1}\text{x}\big)\frac{\text{d}}{\text{dx}}\big(2\sin^{-1}\text{x}\big)$
[Using chain rule]
$=\cos\big(2\sin^{-1}\text{x}\big)\times2\frac{1}{\sqrt{1-\text{x}^2}}$
$=\frac{2\cos\big(2\sin^{-1}\text{x}\big)}{\sqrt{1-\text{x}^2}}$
So,
$\frac{\text{d}}{\text{dx}}\Big(\sin\big(2\sin^{-1}\text{x}\big)\Big)=\frac{2\cos\big(2\sin^{-1}\text{x}\big)}{\sqrt{1-\text{x}^2}}$

A wholesale dealer deals in two kinds, $A$ and $B$ (say) of mixture of nuts. Each kg of mixture $A$ contains $60$ grams of almonds, $30$ grams of cashew nuts and $30$ grams of hazel nuts. Each kg of mixture $B$ contains $30$ grams of almonds, $60$ grams of cashew nuts and $180$ grams of hazel nuts. The remainder of both mixtures is per nuts. The dealer is contemplating to use mixtures $A$ and $B$ to make a bag which will contain at least $240$ grams of almonds, $300$ grams of cashew nuts and $540$ grams of hazel nuts. Mixture $A$ costs Rs. $8$ per kg. and mixture $B$ costs Rs. $12$ per kg. Assuming that mixtures A and B are uniform, use graphical method to determine the number of kg . of each mixture which he should use to minimise the cost of the bag.

Suppose a girl throws a die. If she gets 1 or 2, she tosses a coin three times and notes the number of tails. If she gets 3, 4, 5 or 6, she tosses a coin once and notes whether a 'head' or 'tail' is obtained. If she obtained exactly one 'tail', then what is the probability that she threw 3, 4, 5 or 6 with the die?
