WebHow to: Given a trigonometric equation, solve using algebra Look for a pattern that suggests an algebraic property, such as the difference of squares or a factoring opportunity. … WebTrigonometric equation is an equation involving one or more trigonometric ratios of unknown angles. It is expressed as ratios of sine (sin), cosine (cos), tangent (tan), cotangent (cot), secant (sec), cosecant (cosec) angles. For example, cos 2 x + 5 sin x = 0 is a trigonometric equation.

WebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1.
