Find the value of sin²45 + tan²45

$\sf\large\underline\purple{Solution:–}$

$\sf{\implies sin²45 + tan²45}$

$\sf{\implies (\dfrac{1}{\sqrt{2}})^{2} + {1}^2}$

$\sf{\implies \dfrac{1}{2} + 1}$

$\sf{\implies \dfrac{3}{2}}$

Additional information :–

✦ Trigonometry identities :—

Sin²θ + cos²θ = 1

Sec²θ – tan²θ = 1

Cosec²θ – cot²θ = 1

✦ Reciprocal identities :—

• Cosecθ = 1/sinθ

• secθ =1/cosθ

• cotθ =1/tanθ

• sinθ = 1/cosecθ

• cosθ = 1/secθ

• tanθ = 1/cotθ
