expand (tan(x)+1)^2

expand

(tan (x) + 1)^{2}

tan^{2} (x) + 2 tan (x) + 1

Solution steps

(tan (x) + 1)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(tan (x) + 1)^{2} = tan^{2} (x) + 2 tan (x) \cdot 1 + 1^{2}

= tan^{2} (x) + 2 tan (x) \cdot 1 + 1^{2}

Simplify

tan^{2} (x) + 2 tan (x) \cdot 1 + 1^{2} : tan^{2} (x) + 2 tan (x) + 1

= tan^{2} (x) + 2 tan (x) + 1

(3 + 3 i)^{5}

(1 - sin (θ))^{2}

(2 x + 3) (2 x - 3)

(1 - cos (x)) (1 + sec (x)) (cos (x))

(1 + i)^{6} + (1 - i)^{8}
