To find the component form, u only need to know how to substitute figures for letters. What do I mean by this?

If initial side is (x1,y1)
Then x1 = -1, and y 1 = 16
If the terminal side is x2, y2
Then x2 =1 and y2 =9

This component from p is x2-x1 y2-y1
In this case <[1-(-1)], (9-16)
Which give us
2,-7

If p = x ,y using Pythagorean’s theorem
2(2) + (-7)(7)
4+49
53
Square root of 53 is
7.28010988928
7.3

Why can a problem with extra information be difficult to solve?

Leni [432]

The problems with extra information, are difficult to solve because sometimes, not all data should be used.

Therefore, students begin to doubt the fact that they are not using all the information raised in the problem.

Example:

Problem:

Suppose we have a triangle with a right angle. The problem gives us as data an angle and the sides of the triangle. We want to determine the length of the hypotenuse.

Solution:

Using the Pythagorean theorem we can solve the problem.

The given angle data is an extra information that you should not use for this case.
