Class 10 NCERT Ch-8 (Trigonometry Ratios) EX:-8.1 PART :- 1 | BY MANISH SIR

Hey! Students,
How are you?I hope you are Fine. So Today we study more about trigonometry ratios Ex:-8.1 .





What is Trigonometry Ratios? With all details.








How to introduce trigonometry in class 10?

=For the right ΔABC, right-angled at ∠B, the trigonometric ratios of the ∠A are as follows:
sin A=opposite side/hypotenuse=BC/AC.
cos A=adjacent side/hypotenuse=AB/AC.
tan A=opposite side/adjacent side=BC/AB.
cosec A=hypotenuse/opposite side=AC/BC.
sec A=hypotenuse/adjacent side=AC/AB.
cot A=adjacent side/opposite side=AB/BC.






Trigonometry is one of the most easiest one in mathematics . Just be confident with the formulas , identities , ratio and basic rules . And always understand the problem given to you and then answer it . If your not able to understand according to the question you draw .







Who is the Father of Trigonometry Ratios?

=The father of trigonometry is thought to have been Hipparchus. In the second century BC, the Greek mathematician Hipparchus made the discovery of trigonometry
