Trigonometry basics ∆.....

Hello learners 👋🏼.......

Let's start the new blog on the topic i.e. trigonometry which surrounded by the 6 entities written as follows :-

1. Sin A (Sine of angle A)

2. Cos A (Cosine of angle A)

3. Tan A (Tangent of angle A)

4. Cosec A (Cosecant of angle A)

5. Sec A (Secant of angle A)

6. Cot A (Cotangent of angle A)

Trigonometry is a vast chapter so in this blog we will take only one topic i.e. trigonometric ratios ....

Trigonometric ratios means the relation between the entities and the angle of triangle and the sides of the triangle 📐......

Let's first see the relation between these entities with one another.....

Now let's see the relation between the entities and the angle and sides of the right angled triangle....

May be you all know the tricks of learning this trigonometric ratios still let me tell you the trick.....

Sin A      Cos A       Tan A

Pandit     Badri     Prasad

   Har        Har        Bhole

Sin A =  P       Cos A =   B              Tan A =  P

               H                       H                              B

Where P is perpendicular ,

              B is base              &

              H is hypotenuse .....

I hope this trick will help you to memorize the formulas.....

Now let me give you some questions to check your understanding....

Questions    - -> Solve 

1.  Find Sin A, if in triangle AB = 3 and BC = 4 

2. If Cot A = 7/8 , find Tan A and Sin A

Do attempt the questions......👉🏼....
