What I am making right now is a program that will show you the steps when it is doing trigonometry. For some reason, when the opposite is divided by, lets say, sin(30), it always results in a negative number. Why is that? The error appears to be occurring at this line:
cout << "Therefore x = " << length / sin (angle);
You need to convert it to radians:
sin (angle * PI/180);
UPDATE:
What is PI?
World Record values of PI
The sin function takes input as radian:
sin (angle * M_PI/180);
where M_PI = 3.141...., which is a constant.

I am having some troubles where my code is only displaying the first section I have inputed "Sphere" and is not letting me input any other values when I go to Debug.
The basis of the code is to have the user choose a selction, and be able to input values to find the surface areas and volumes of a shape. Below is my code. (Also I am new to this so if there are any pointers I would greatly appreciate it!)
This is for an exam I have so just some input as to where I am going wrong would be great. I want to learn it not have the whole thing completed for me

Trying to let only numbers be a vaild input for a quadratic equation solver. I used bool and broke my code and no matter the input it just gives me my error message even if it is a vaild input.
After the progarm ask you to confirm the coefficients are correct, even if you put Y you get the " Please input a number. Please try again". how do you fix this?
I added the bool becasue that what my teacher showed me to use for checking inputs, very new to c++ and coding. I just added the whole code, the HW was to update HW 5 to do a few things more. I broke it trying to check inputs, when adding bool.

I am building a program that gets the angle from the user and then convert it into radian before calculating its Sine and Cosine values. When I run this code it tells me that the angle from "int cos(angle)" was not defined, so I tried moving it into the if loop for choice 2, but it didn't solve the issue. It also says that cos(angle) cannot be used as a function when I tried to trigger it from the if loop for choice 2. Any ideas on this?
I actually made a similar program using Python back then, and this method that I used to write the program worked. I know there are some differences between Python and C++, but I thought the general idea would still apply.
Thanks in advance.
Cheers.
In the function definition/declaration you must mention the argument data type.

You get that error because you try to call a function distance() that is declared in your code by
float distance(float x, float y, float a, float b);
but not defined.
I am very new at C++.
I wrote this code below which is supposed to tell me if 2 lines have an intersection point, so I figured two lines with equal "M" in the y=Mx+B equation should not intersect and all others would.
The program seems to be understanding this, but unless the slope of the inputted line segment is 0 it outputs inf or -inf.
why is this happening?

This line:
LineSeg1 = ((pointB[1]-pointA[1])/(pointB[0]-pointB[0]));
has a divide by zero error.
I believe the equation should be:
LineSeg1 = ((pointB[1]-pointA[1])/(pointB[0]-pointA[0]));
