Question

A can do a work in 2 days and B can do a work in 8 days if they worked together in how many days will they complete it​

Answer 1

Answer:Trignomentry :-

sin^2A+cos^2A = 1

sec^2A-tan^2A = 1

cosec^2A = 1 + cot^2A

cosec A = 1/ sin A

sec A = 1/ cos A

tan A = 1/ cot A

tan A = sin A / cos A

☆ The values of trigonometry ratios for angle 0°, 30°, 45°, 60° and 90°

☆ Value of sin A or cos A can never be more than 1.

☆ Value of sec A or codec is always more than or equal to 1.
