★$\huge\bf{\green{\underline{Explanation:-}}}$

tana + cota =2

take square both sides

(tana + cota)² = 2²

tan²a + cot²a +2tana.cota =4

we Know,

tana =1/cota

so,

tan² a + cot²a +2 = 4

tan²a + cot² a = 4 -2 = 2

Answer 2

tana + cota =2

take square both sides

(tana + cota)² = 2²

tan²a + cot²a +2tana.cota =4

we Know,

tana =1/cota

so,

tan² a + cot²a +2 = 4

tan²a + cot² a = 4 -2 = 2
