Similarly, when we can learn here the trigonometric identities for supplementary angles. sin (180°- θ) = sinθ cos (180°- θ) = -cos θ cosec (180°- θ) = cosec θ sec (180°- θ)= -sec θ tan (180°- θ) = -tan θ

Web20 dec. 2024 · The identity 1 + cot2θ = csc2θ is found by rewriting the left side of the equation in terms of sine and cosine. Prove: 1 + cot2θ = csc2θ. 1 + cot2θ = (1 + cos2θ sin2θ) Rewrite the left side = (sin2θ sin2θ) + (cos2θ sin2θ) Write both terms with a … Web26 mrt. 2016 · solve for the sine in terms of cosine and replace each cosine with 1 over its reciprocal (which is secant): The radical has a fraction in it. A better form is to simplify that fraction, so find a common denominator and split the fraction into two radicals — the bottom one of which you can further simplify: in which or in which
