Trigonometric Angle Calculation

I always had trouble in calculating the angles because I did not remind the table that’s why I had trouble in calculating the angle by the table. All my friends remembered the table but it was difficult to me to  pass the exam paper without angle, so I started harassing my teacher and asked him, “Sir, there is no other way or method  .” He helped me and make a  short trick with his help. That trick I tell you

You have always used this table


Another method 


We can Calculate the angle by the left and right method.
 

As you know these are  some basic angle


0 °    30 °     45 °    60 °     90°

 These are five angles that we get out of


Eg sin30 °, sin45 ° etc
Tan45 °, tan 90 °, tan30 ° etc.
Cos0 ° cos30 ° etc

 You just have to remember three formulas (L = left)
(R = right)

1. SinΦ = √L / 4 
2.cosΦ = √R / 4 
3. TanΦ= √L / R 

With example

Suppose we have to find the value of sin30 °






Formula is sin = √L / 4

Left of  30 °  is an angle 0 °  so L   = 1
By formula

Sin = √L / 4 and L = 1

Sin = √1 / 4 so value is 1/2

If you want to find the value of Cosec 30 ° is reciprocal of sin°  means reciprocal of 1/2 is cosec 30 ° = 2

One more example

Suppose we get the value of cos 30 °

The formula of cos° is √R / 4

Cos 30 ° right = 3 angle  45 °, 60 °, 90 °

Therefore R = 3

Formula is

Cos = √ R / 4 and R = 3

Cos30 °. = √3 / √4 means  √3 / 2                                        (sec° reciprocal of cos°)

One more example is

Tan45 ° is ????

By formula tan ° = √L / √R

Tan45 ° Left  Angle is 0 ° and 30 ° and Right Angle is 60 ° and 90 °

L = 2 and R = 2

By formula tan ° = √L / √R

Tan 45 ° = √2 / √2. = 1

Value of Cot° is Reciprocal of tan° value

  1. Most of the students always had trouble in calculating the angles. Here they can find their solutions. You have well explained through diagrams which will help students to understand easily. Trigonometry angles are the angles given by the ratios of the trigonometric functions. Trigonometry deals with the study of the relationship between angles and the sides of a triangle. Before discussing the trig angles, students have to look at the definition of angle, and its related terminologies. Trigonometry is an important topic for Class 10, 11 and 12. Hence, it is required for students to learn the concept in a detailed manner to excel in the exam.

  2. The visuals and the pleased of your article is extraordinary and these types of are applied in just righ vogue in direction of demonstrate what exaclty oneself will need in direction of proportion.
