हल कीजिए - ` tan^(3) theta - 3 tan theta = 0`

Explanation

` tan ^(3) theta - 3 tan theta = 0 `
` rArr tan theta ( tan^(2) theta - 3) = 0 `
` rArr tan theta = 0 " या " tan^(2) theta - 3 = 0 `
यदि ` tan theta = 0 ` तो ,
` theta = n pi`
यदि ` tan^(2) theta - 3 = 0 ,` तो
` tan^(2) theta = 3 = (sqrt(3))^(2) = tan ^(2) . pi/3`
` rArr theta = n pi pm pi/3 `
