Maths Formulas For Class 10 Chapter Introduction To Trigonome More formulas for class 10. algebra formulas for class 10; geometry formulas for class 10; maths formulas for class 10; mensuration formulas class 10; solved examples. example 1: if sin a = ⅗, then find the value of cos a and cot a. solution: given, sin a = ⅗. using the identity, sin 2 a cos 2 a = 1, cos 2 a = 1 – (⅗) 2 = (25 – 9. Solution: let us assume a right angled triangle abc, right angled at b. given: 15 cot a = 8. so, cot a = 8 15. we know that, cot function is the equal to the ratio of length of the adjacent side to the opposite side. therefore, cot a = adjacent side opposite side = ab bc = 8 15. let ab be 8k and bc will be 15k.
