How to Find Co-terminal Angles and Reference Angles

How to Find Co-terminal Angles and Reference Angles


- Co-terminal angles are equal angles.
- To find a co-terminal of an angle, add or subtract \(360\) degrees (or \(2π\) for radians) to the given angle.
- Reference angle is the smallest angle that you can make from the terminal side of an angle with the \(x-\)axis.

How to Sketch Angles in Standard Position


A standard-position angle has its vertex at the plane's origin. Along the positive \(x\)-axis is where its initial ray (beginning side) is located. From the beginning side, its terminal ray (finishing side) travels counterclockwise.

How to Find Trigonometric Ratios of General Angles

How to Find Trigonometric Ratios of General Angles


Sine, Cosine, Tangent, Cotangent, Secant, and Cosecant are trigonometric ratios. For these trigonometric ratios, the standard angles are \(0, \ 30, \ 45, \ 60,\) and \(90\) degrees. These angles can also be shown using radians, such as \(0, \ \frac{π}{6}, \ \frac{π}{4}, \ \frac{π}{3},\) and \(\frac{π}{2}\) . In trigonometry, these angles are most regularly and frequently used. To solve many problems, you need to know the values of these trigonometry angles.

How to Solve Finite Geometric Series


Finite Geometric Series:  The sum of a geometric series is finite when the absolute value of the ratio is less than 1.

What is the Difference between Arithmetic and Geometric Sequence

What is the Difference between Arithmetic and Geometric Sequence


Both arithmetic and geometric sequences follow a pattern, so they are similar. The next number is found in an arithmetic sequence by adding or subtracting the same number. In the same way, the following number in a geometric sequence is found by multiplying or dividing the same number. But the two kinds of sequences are very different from each other.
In this article, we will talk about the big differences between an arithmetic sequence and a geometric sequence.
