Solve 4sin2θ + 4cosθ - 5 0 for 0° ≤ θ 180°
WebIn trigonometrical ratios of angles (180° - θ) we will find the relation between all six trigonometrical ratios. We know that, sin (90° + θ) = cos θ. cos (90° + θ) = - sin θ. tan (90° + θ) = - cot θ. csc (90° + θ) = sec θ. sec ( 90° + θ) = - csc θ. cot ( 90° + θ) = - tan θ. and.
