Please I want a solution to the question

Question

Prove that (sin×tan) \cos =1

Answer 1

There seems to be a mistake here: you mixed up the sine with the cosine. The correct expression is supposed to be:

(Cos×tan)/sin=1

Recall that tan =sin/cos...

Answer 2

(sinx)(tanx)/(cosx) = 1

sinx(sinx/cosx)/cosx =1

=sin^2x/cos^2x =1

sin^2x = cos^2x

x = pi/4 +npi/2 where n= any integer

or

x = 45 + 90n degrees where n= any integer

check the solution

sin45(tan45)/cos45 = (.707)(1)/(.707) = 1

or

maybe the problem was intended to be

cosx(tanx)/sinx = 1

then

cosx(sinx/cosx)/sinx = 1

cosx/sinx)(sinx/sinx) = 1

(1)(1) = 1

then x can = any value of degrees or radians
