Question

what is the value expression (cosesc (75°-thetha)-sec(15°-thetha)-tan(55-thetha)+cot(35°-thetha)​

Answer 1

Answer:

cosec(75∘+θ)−sec(15∘−θ)−tan(55∘+θ)+cot(35∘ . Now complementary of cosec(75∘+θ) is sec[90∘−(75∘+θ)]=sec(15∘−θ) . So, the correct answer is “0”. Note: Sine, cosine, tangent, cotangent, cosecant and secant are six main trigonometric ratios,.
