CBSE Class 10 Maths Trigonometry trigonometric identities
|
Use identity.
Introduction to Trigonometry
Recall trigonometric identities
\\(sin^{2} \\theta + \\frac{1}{1+tan^{2} \\theta} = sin^2 \\theta + \\frac{1}{sec^{2} \\theta}\\) = \\(sin^{2} \\theta + cos^{2} \\theta = 1\\)
Trigonometry
Using trigonometric identities
sin2Ó¨ \\(\\times \\) cosec2Ó¨ = 1
\\(sin^{2}\\Theta +\\cos^{2}\\Theta =1\\)
Use the knowledge of Trigonometric Identities.
(sec2 θ-1)=tan2θ (cosec2 θ-1)=cot2θ tanθ cotθ=1
