As a significant branch in mathematics, trigonometry has complex questions that
students find hard to answer. What is important to note to make the subject
easy is to understand the trigonometric functions: cot, cosec, sec, tan,
cos, and sin. These six functions are vital to learning as all trig questions
revolve around them. The tips below will help you to handle the problems with
ease.
Learn the Basics
As with any other branch of mathematics, trig functions also have their basics. To
know how to solve any equations on the field, you will need to learn the
basics. Once you understand them, you will have an easy time approaching any
question given.
Understand the Periodic Property
Trig functions return to their exact value at regular intervals, making them
periodic. When you get a question, the problem specifies the period. You have
to look for the solution arc. However, be careful and check the answers as trig
equations can be tricky, leading to mistakes. You can confirm using a graphing
calculator to graph the trig equation whose answer will be in decimals.
Keep Practicing
Like any branch of math, trig equations also require practice to grasp them. You will
learn the rules and formulas of trig functions easily by practicing them daily.
When you get stuck, you will have time to ask your tutor for an explanation. However,
how can you solve trigonometric functions easily? You can find reliable online platforms. You will find several examples of trig questions and their answers. As you go through the list, you will learn how to solve any other related function as the approach will be the same.
Know the Approaches
To tackle equations efficiently, learn how to approach them the right way. When
there is only one function in an equation, you will handle it as a basic trigonometric equation. If the equation has two or more functions, you can solve it using two approaches. The first one is by transforming the equation to a product inside the form. The second approach is by turning the given equation into an equation with only one unique function as a variable.
Dealing With Angles
When you want to find a function of an angle, it is good to note that trig equations
are about numbers and not angles. Therefore, you will be finding all numbers that you can substitute for the variable in a given equation and make it true. However, to make it simpler. Worry about the angles first. The variables will follow later.
Conclusion
Solving trig identities requires you to understand the basics first; otherwise, you will have difficulty tackling any question. Learning how to deal with angles, understanding the periodic property, and most importantly, practice is crucial for you to pass.
