Show that 1/cosθ + tanθ = cosθ/1-sinθ
I have got as far as changing tanθ into sinθ/cosθ but not sure what to do from here.
Now you need to figure out how to change it into the correct form,
if you notice the cos on the bottom moves to the top, which to me would suggest you can make the top have a cos^2 in it. you could use the fact that cos^2+sin^2=1 and multiply both top and bottom by the same thing to get the cos^2 you want.
ok so it is 1+sinΘ/cos Θ on the left.. multiply numerator and denominator with 1-sinΘ .. ull get cos2Θ/cos Θ(1-sinΘ) ... common factors remove .. then ull get the right hand side yea
