[PRECALC] Verify the following trigonometric identity using sin2x + cos2x = 1

frosja888 [35]

Answer:

See below ~

Step-by-step explanation:

Identities :

cot x = cos x / sin x
sin²x + cos²x = 1

Changing the Left Hand Side (LHS) :

1/cot x + cotx
1/(cos x / sin x) + cos x / sin x
sin x / cos x + cos x / sin x
Take (sin x)(cos x) as the LCM (Least Common Multiple)
sin x (sin x) + cos x (cos x) / (sin x) (cos x)
sin²x + cos²x / cos x sin x
1/cos x sin x
Equal to the RHS
