Ex 9.3, 1 - Find general solution: dy/dx = 1 - cos x/1 cosx
Ex 9.3, 1 For each of the differential equations in Exercises 1 to 10, find the general solution : 𝑑𝑦/𝑑𝑥=(1 − cos⁡𝑥)/(1 cos⁡𝑥 ) 𝑑𝑦/𝑑𝑥 = (1 − cos⁡𝑥)/(1 cos⁡𝑥 )We know that cos 2x = 2cos2 x − 1Putting x = 𝑥/2 cos 2𝑥/2 = 2 cos2 𝑥/2 − 1 cos x = 2 cos2 𝑥/2 − 1 1 cos
