solve for x : ( by radian)
1)cotx= 3
2)secx = 0.5
<<<and thanks >>>
1) Same as tan x = 1/3. Use a calculator. I get 0.321 radians
2) sec x = 0.5 is not possible. The absolute value of the secant must be one or more.
<< Thanks drwls for your help >>

tan(3x) + 1 = sec(3x) Thanks, pretend 3x equals x so tanx + 1 = secx we know the law that 1 + tanx = secx so tanx + 1 becomes secx and... secx = secx sec(3x) = sec(3x) [just put 3x back in for x you don't really have to change 3x …

How do you find: cot(5pie/4)? you have to know that cotx = 1/tanx so you could just trustfully change your calculator to radians enter 5*pi/4, press =, press +/, then press Tan, =, then the 1/x key you should get 1 or... you could

My previous question: Verify that (secx/sinx)*(cotx/cscx)=cscx is an identity. (secx/sinx)*(cotx/cscx) = (secx/cscx)(cotx/sinx) = (sinx/cosx)*cotx*(1/sinx) "The last steps should be obvious" Not to me. I can convert (sinx/cosx) to …
