Notice that the left side expresses the expansion of sine of double angle, hence the given identity `(2 tan theta)/(1 tan^2 theta ) = sin 2 theta ` is checked Approved by eNotes Editorial TeamI'm having trouble on where to begin proving identities I must prove that 2 tan theta /(1 tan^2 theta) = sin 2theta Hi Charmaine, In a problem like this when I don't immediately see something useful I write everything in terms of sines and cosines and then see if I can manipulate both sides to make them equal$\cos{2\theta}$ $\,=\,$ $\dfrac{1\tan^2{\theta}}{1\tan^2{\theta}}$ A mathematical identity that expresses the expansion of cosine of double angle in terms of tan squared of angle is called the cosine of double angle identity in tangent Introduction Let the theta be an angle of a right triangle

Prove the following trigonometric identity $$1 \tan^2\theta = \sec^2\theta$$ I'm curious to know of the different ways of proving this depending on different characterizations of tangent and seIf sec theta = 1 1/4, then tan theta/2 is equal to · $$\cos^{1} \theta \neq \frac{1}{\cos \theta}$$ That is why I prefer to use the arc notation as in $\arccos \theta$ The notations $\cos^{1} \theta$ and $\arccos \theta$ represent the same thing, which is, roughly speaking, the inverse of $\cos \theta$ (although it is not a true inverse since $\cos$ is not injective) Back to your question
Given that Tan ¢ 1/ Tan ¢ = 2 On squaring both sides we get, ( Tan ¢ 1/Tan ¢ )² = (2)² We know that, ( A B)² = ( A)² ( B)² 2 × A × B ( Tan² ¢ ) ( 1/Tan² ¢ ) 2 × Tan ¢ × 1/Tan ¢ = 4 ( Tan² ¢ ) ( 1/Tan² ¢ ) 2 = 4 ( Tan² ¢ ) ( 1/Tan² ¢ ) = 42Select the correct option from the given alternatives If θ = 60°, then 1tan2θ2tanθ is equal toYou can use this fact to help you keep straight that cosecant goes with sine and secant goes with cosine The following (particularly the first of the three below) are called "Pythagorean" identities sin 2 (t) cos 2 (t) = 1 tan 2
