Question

the value of expression [cosec(75° + theta - sec (15° - theta) - tan (55° + theta) + cot (35° - theta) is 0......write the steps ​

Answer 1

Answer:

cosec(750+θ)−sec(150−θ)−tan(550+θ)+cot(350−θ)

=sec(900−750−θ)−sec(150−θ)−cot(900−550−θ)+cot(350−θ)

=sec(150−θ)−sec(150−θ)−cot(350+θ)+cot(350+θ)

=0

Answer 2

cosec(75° +θ)−sec(15°−θ)−tan(55°+θ)+cot(35° −θ)

=sec(90°−75 ° −θ)−sec(15° −θ)−cot(90° −55° −θ)+cot(35° −θ)

=sec(15° −θ)−sec(15° −θ)−cot(35°+θ)+cot(35°+θ)

=0
