Domain of Function

We need to make different cases for each expression which can be undefined. For instance square root is not always well defined (here you have two of them so two cases possibly) and log is also not always well defined. Make those cases. Solve them. Take intersection of all three because we need all three of them to be true together. Youll be having the domain of definition

Interesting questions. I have never read anything about it to be honest but if I were to guess, degree is defined for algebraic functions (polynomials) and therefore generalising the same idea in differential means we need to talk about degree for algebraic functions. Here in this question sin x is a transcendental function which cannot be expressed in the form of a polynomial of constant degree (like if you use series expansion then it will be having infinitely many terms which means the degree is infinite or undefined). Another reasoning can be to standardize a definition so that all mathematicians across the globe are on the same page.

So you gotta find mean using one of the three known methods:- Direct, Assumed Mean, or Step Deviation

It gives an approximation (empirical formula) not an exact answer. Useful to discard wrong options but not good in case of NAT questions

Gotta put the values of x and y and simplify. Remember to use the properties of omega while simplifying. Try once again

I don't know why they don't write it properly. Authors gotta understand that even fourth root and further have imaginary roots yaar.

is the first thing used to find the constant? and the 2nd says put x as 2?

No worries. No doubts are dumb doubts. Just put it in the doubts channel. Someone, if not me, will come to rescue. Happy learning

For y=-x, the angle will be 135. Tan135 is negative

So the red line will probably make an angle between 0 and 90 with positive x-axis. Slope will be tan of this angle. For y=x the angle should be 45 degrees

not really. It has to do with the slope of the line.

Nope. Red one will be y=x (assuming slope is 1) and blue one will be y=-x (assuming slope is -1)
