Question

prove that the identy of trignometry

Answer 1

Answer:

identity 1

$sin {}^{2} \alpha + \cos {}^{2} \alpha = 1$

take alpha as any value but alpha should be same

$\sin {}^{2} 30 + \cos {}^{2} 30$

next

Answer 2

Answer:

but where is the question..

u can use the following formulas to prove..

sin²∅ + cos²∅ = 1

* sec²∅ - tan² = 1

* cosec²∅ - cot²∅ = 1
