## Do You Hate Trigonometry?

According to the traditional definition, “trigonometry is the branch of mathematics that deals with the relationships between the sides and angles of a triangle.”

Not your cup of tea, huh? Try the following steps:

1. Take index cards and cut them into small pieces. It is small enough to carry in your pocket and large enough to clearly write one trigonometric identity.

2. Start writing 1 ID on the back of 1 index card. An example would be Sin2 (theta) + Cos2 (theta) = 1. Now, divide all terms by Sin2 (theta). Do it yourself and see the result. Copy your work neatly onto the back of an index card. Write today’s date. This process will take a maximum of 15 minutes.

3. Next, divide all terms by Cos2 (theta). Write the job neatly on the back of another index card and date it.

4. Make similar classifications of other identities.

5. If you do this once a day for just 3 weeks, you’ll know which formula to use the next time a trigonometry problem stares you in the face. If you still have problems, you can always ask your teacher at school or you can send the problem to a teacher online. A decent online math tutor should be able to help.

Let’s try to solve a simple problem based on the practical application of trigonometry:

Q) A kite is flying at a height of 75 meters above level ground, attached to a string at an angle of 60 degrees to the horizontal. Find the length of the wire to the nearest meter.

Step 1: To start, first draw the required diagram according to the problem.

P

MO

Step2: Try to match the diagram to the given problem

Clarify the necessary recommendations:

Let ‘P’ represent the position of the kite, and MP = 75 meters (height of the kite)

And the thread is held at point O, the Angle
