Here you will learn some trigonometry examples for better understanding of trigonometry concepts. Example 1 : \(sin5x + sin2x โ sinx\over {cos5x + 2cos3x + 2cos^x + cosx}\) is equal to โ Solution : L.H.S. = \(2sin2xcos3x + sin2x\over{2cos3x.cos2x + 2cos3x + 2cos^2x}\) = \(sin2x[2cos3x+1]\over {2[cos3x(cos2x+1)+(cos^2x)]}\) = \(sin2x[2cos3x+1]\over {2[cos3x(2cos^2x)+(cos^2x)]}\) = \(sin2x[2cos3x+1]\over {2cos^2x(2cos3x+1)}\) = tanx Example โฆ
Here, you will learn conditional trigonometric identities and maximum and minimum value in trigonometry. Letโs begin โ Maximum and Minimum values in Trigonometry Expressions : (i)ย acos\(\theta\) + bcos\(\theta\) will always lie in the interval [-\(\sqrt{a^2+b^2}\), \(\sqrt{a^2+b^2}\)] i.e. the maximum and minimum values are \(\sqrt{a^2+b^2}\), -\(\sqrt{a^2+b^2}\) respectively. (ii)ย Minimum value of \(a^2tan^2\theta\) + \(b^2\tan^2\theta\) = โฆ
