Question

First answer will get medal!!


What happens when you multiply tan and cos, cos and sin, sec and sin.

Answer 1

tan and cos: tan=sin/cos sin*cos/cos= sin/1.
cos and sin: cos*sin=cos*sin, no simplification here.
sec and sin: sec=1/cos, sin*(1/cos)=sin/cos=tan.

Answer 2

thanks so much!

Answer 3

i dont get the tan and cos

Answer 4

so tan = sin/cos. (sin/cos) * cos = (sin*cos)/(cos). because there is a cos in the numerator and denominator, you can cross the cos's off, leaving you with sin/1.

Answer 5

why does tan equal
sin / cos

Answer 6

that's just the definition of tan

Answer 7

sec= 1/cos
csc= 1/sin
tan= sin/cos
cot= cos/sin
sin is normal, just sin
cos is normal, just cos
all of them are related to sin and cos

Answer 8

ok
