Answer:
Step-by-step explanation:
Given the differential (d/dx)(cos−1(x)), to find the equivalent formula we will differentiate the inverse function using chain rule as shown below;
let;
Therefore;
Since x = cos y from the above substitute;
Hence, gives the required proof
The distance between the two points would be the square root of 40. Hope this helped!
