Additional Math – Trigonometry – Prove the Identity Cos x/ (1- Sin x) = Tan x + Sec x – Tuition with Jason – Math Specialist
1-Substitution method( part 1 trigo) .int(1/cos(x))= int(sec(x) primitive en quelques secondes quand on choisit la bonne variable
Ex 7.3, 8 - Integrate 1 - cos x / 1 + cos x - Chapter 7 Class 12
SOLVED: Formulas: 1. 13 sin x + cos x = 1 - cos(2x) - 2sin x = 2 - 1 + cos(2x) - 3cos x = 2. 2. 4 sin(2x) = 2sin
Ex 7.3, 21 - Integrate sin-1 (cos x) - Chapter 7 Class 12
