sinØ (1+ tanØ) + cosØ(1+ cotØ) = (secØ + cosecØ)
Secø + tanø=x
Then find the value of secø
tan1/2=cscø-cotø
As the answer to:
(tanØ * cosØ/ sinØ) + cotØ * sinØ * tanØ* cscØ I got 2, is that correct?
Prove the following:
1/(tanØ - secØ ) + 1/(tanØ + secØ) = -2tanØ (1 - sinØ)/(1 + sinØ) = sec^2Ø - 2secØtanØ + tan^2Ø
Prove that:Tanø+sinø/tanø-sinø=secø+1/secø-1
x=2cosø-sinø and y=cosø-3sinø then prove that 2x+y-2xy=5
Convert the polar equation to rectangular form:
r = -2cosø - 2sinø
Tanø(secø+2)
If sinø=4/5 find the value of cosecø/1+cotø
