WebTrigonometric Ratios of Compound Angles An angle made up of the algebraic sum of two or more angles is called a compound angle. Some of the formulae and results regarding compound angles are: sin (A + B) = sinA cosB + coA sinB sin (A – B) = sinA cosB – cosA sinB cos (A + B) = cosA cosB – sinA sinB cos (A – B) = cosA cosB + sinA sinB WebDec 10, 2024 · Trigonometrical Ratios or Functions. In the right angled triangle OMP, we have base = OM = x, perpendicular =PM = y and hypotenues = OP =r. We define the …

what is t-ratio of allied angles - Brainly.in

WebApr 3, 2024 · The allied angle (90o + θ) is in the second quadrant and 90o = 1 x 90o is odd multiplicative of 90o, so the trigonometric ratios sin and cosec of (90o + θ) will be positive and other will be negative and all the trigonometric ratios are changed in pairs. Hence, we conclude that sin (90o + θ) = +cosθ cos (90o + θ) = -sinθ tan (90o + θ) = -cotθ WebSep 23, 2015 · sin(600^"o") = -sqrt(3)/2 cos(600^"o") = -1/2 sec(600^"o") = -2 csc(600^"o") = -(2sqrt(3))/3 tan(600^"o") = sqrt3 cot(600^"o") = sqrt(3)/3 First thing, let's see how many full loops we can get out of that angle, theta = 600^"o" = 360^"o" + 240^"o" = 2*360^"o" - 120^"o" Why this is important, you may ask? It's because every 360^"o" degrees we have a full loop … folsom autotech coupons
