Operations with functions and finding the domain of each

👉 Learn how to apply operations to functions such as adding, subtracting, multiplying, and dividing to two functions. To add/subtract/multiply or divide two functions, we algebraically add/subtract/multiply or add the rules (contents) of the two functions. We will then simplify the sum, difference, product, and quotient by combining like terms. Lastly, we will determine the domain of each.

why is the back of his head a negative cosine function on the interval [-pi/2, pi/2]

[Khatalyz]

Why is that the domain? Do you have any other video where you explain how to find the domain?, thank you

[استمعبقلبك-سو]

So, in division only I must get the domain from the original ? not from the result
