How could you tell if tan is negative or positive in a quadrant Example in quadrant II cos - and sin is plus but what is tan?

There's a mnemonic for this: All Students Take Calculus. Starting in the first quadrant, and moving counterclockwise until the last, give each quadrant the first letter of thos words in order. A represents all 3, s represents sine, t represents tangent, and c represents cosine. If the letter appears in a quadrant, it is positive there. If not, it is negative there.
In quadrant 2, only sine is positive.

What are the coordinates of a point that could be in each of the four quadrants?
The coordinates must be as follows: First quadrant: positive, positive Second quadrant: negative, positive Third quadrant: negative, negative Fourth quadrant: positive, negative
What is negative subtracted by a positive?
The Answer could be neither positive nor negative because the positivve could be bigger than the negative or the neagative could be bigger than the positive
When you add a positive and a negative what does it become?
the answer could be negative or positive depending on whether the negative number you're adding is bigger than the positive number
What doe a negative plus a positive equal?
It depends. It could equal either a negative number or a positive number, depending whether the negative number or the positive number is larger in absolute value. For example, -5 + 3 = -2, but -5 + 12 = +7.
What is angle of reference in trigonometry?
This is a VERY important question and I am glad you asked it. First you have to remember that in drawing angles we think of 4 quadrants. Think of the XY plane - the first quadrant is where BOTH X and Y are positive. In the 2nd quadrant the X is negative and the Y is positive. In the 3rd quadrant the X and the Y are negative. In the 4th quadrant the X is positive and the Y is negative. Normally when we draw an angle we draw an angle less than 90 degrees. However, we can draw any angle we want from 0 to 360. However that angle can be represented by an angle less than 90 degrees in a certain quadrant. Take an angle like 120 degrees. That angle is the same as a 60 degree angle in the 2nd quadrant. A 210 degree angle is the same as a 30 degree angle in the 3rd quadrant. A 359 degree angle is the same as a 1 degree angle in the 4th quadrant. Those smaller angles are reference angles. This explanation would be better if I could insert graphs. I have attached a link to a picture. Alpha is the angle and Beta is the reference angle.

What could i do to turn my child's negative attitude into a positive one?
To turn a negative attitude into a positive one it is important to lead by example. A child will watch you and if they see you being positive they will also be positive.
When you add a positive and a negative what does it become?
the answer could be negative or positive depending on whether the negative number you're adding is bigger than the positive number
Can an A positive father and a B positive mother have a B negative child?
If the mother is A negative, and the father is B positive, they could have children who are A negative, A positive, B negative, B positive, AB negative, AB positive, O negative, or O positive.

What is the positive and negative of McDonald?
Positive aspects of McDonald is that it's quick and convenient and very handy for someone in a hurry. Negative could be that the menu is not sufficiently varied, for example, no vegetables with the exception of potatoes.

When a negative number is cubed is it negative or a positive number?
I think that it's a negative number, as a negative times a negative is a positive, and a positive times a negative is a negative, but I could be wrong. (DUN-DUN--DUUUUUN...)
What will be the difference when subtracting two integers with different signs?
Subtracting: Positive - Negative = Positive Negative - Positive = Negative No that is not the way it goes. It is positive+negetive=either counting on which integer is bigger negative+negative=positive positive+positive=positive positive x negetive=negative negative x postitve= negative negative/positive=negative positive/negative=negetive thanks The top is right though because subtracting a negative is like adding so you could never get a negative and subtracting from a positive from negative will always be a negative. The question was for integers with different signs so you don't need to do "positive + positive"
When you have a negative and positive in math does it become a negative?
It depends on what you do with the negative and positive. If you multiply or divide a positive number and a negative number, then the answer is negative. If you add or subtract a positive number and a negative number, the answer could be negative or positive depending on the numbers involved. If you put a negative sign in front of a positive number, the result is a negative number. If you put a positive sign in front of a negative number (like +(-7)), the result is still negative.
Mark is thinking of two numbers his two numbers have a positive sum but they have a negative product give an example of what his answer could be?
10, -9 sum is 1 product is -90. any two numbers one positive one negative, positive has to be larger
