Question

Help please
The acute angle x radians is such that tanx=k, where k is a positive constant. Express in terms of k...
i) tan(pi-x)
ii) tan (1/2pi-x)
iii)sinx

Answer 1

2

Answer 2

tan (pi/2 - x) = tanx

Answer 3

property

Answer 4

But the answers 1/k for part two

Answer 5

oh , u need to evaluate , huh?

Answer 6

okay...

Answer 7

1) tan(pi-x) = -tanx = -k
2)

Answer 8

tan(pi/2 - x) = tan(90degrees - x) = cotx = 1/k

Answer 9

tan(pi-x) i think is the answer

Answer 10

sinx / cosx = tanx
sinx = tanx * cosx = kcosx

Answer 11

gottit ?

Answer 12

Sweet cheers man, appreciate it

Answer 13

no probs , mate !!
