Which is equivalent to sin^-1(tan(pi/4)) ? Give your answer in radians.
aleksklad [387]
We are to find the value of sin^{-1}(tan( \frac{ \pi }{4}))

First we evaluate tan(π/4). The value of tan(π/4) is 1. 

So, 

sin^{-1}(tan( \frac{ \pi }{4})) =sin^{-1} (1)

sin(π/2) = 1
So,
sin^{-1}(1)= \frac{ \pi }{2}

Thus, we can write:

sin^{-1}(tan( \frac{ \pi }{4}))= \frac{ \pi }{2} radians.

So, the answer to this question is π/2 radians.

At big bens bakery 48 chocolate donuts were made,which is 6 times the number of cream filled donuts made.How many more chocolate
ratelena [41]

Answer:

The number of chocolate made donuts is 40 more than cream filed donuts

Step-by-step explanation:

Given as :

The number of chocolate donuts made = 48

The number of chocolate donuts is 6 times the number of cream filled donuts

So, Let the number of cream filled donuts = x

So, number of chocolate donuts made = 6\times x

∴    6\times x  = 48

Or,  x = \frac{48}{6} = 8

So, the number of cream filled donuts = 8

Now ,

The number of chocolate donuts made -  the number of cream filled donuts = 48 - 8 = 40

So ,  The number of chocolate made donuts is 40 more than cream filed donuts  Answer
