WebStatement 1:If in a triangle sin 2 A + sin 2 B + s i n 2 C = 2, then one of the angles must be 9 0 ∘. Reason Statement 2: For any triangle, sin 2 A + sin 2 B + s i n 2 C = 2 + 2 cos A cos B cos C WebSin3x. Sin3x gives the value of the sine trigonometric function for triple angle. On the other hand, sin^3x is the whole cube of the sine function. Sin3x is a triple angle identity in trigonometry. The expansion of sin3x formula can be derived using the angle addition identity of the sine function and it involves the term sin^3x (sin cube x).
WebSep 7, 2024 · Right angle triangle is one which one of the angle must be 90 degree. sin (40-x)= cos (3x) According to trigonometry identity cosθ= sin (90-θ) sin(40-x)= sin (90-3x) (sin on both the sides gets cancelled) Therefore:-40-x= 90-3x. 3x-x=90-40 .
