How To Do Secant On A Calculator

Above the normal sin cos and tan buttons it says sin 1 cos 1 and tan 1.

This sec x calculator provides the corresponding values of the angles in secant. First you need to determine what information is available to you. Remember that secant cosecant and cotangent are all reciprocals but you typically won t find a button for them on your calculator. If your calculator has brackets i would do.

Csc sec and cot are just the inverses of sin cos and tan. Evaluate for the value of the function at the x values you set up using a calculator. 1 cos x 2 so bracket 1 fraction cos x bracket squared. So if you want the cosecant of 5 just do 1 sin5.

The secant can be calculated using known trigonometric properties if the angle is known but it also can be calculated through simply the equation of h a where h is the length of the hypotenuse of a triangle and a is the length of the adjacent side. How do i use cosecant secant cotangent on my calculator. 8 report 2 years ago 8 i mean it doesn t matter if squared is bracketed. There might not be buttons for the secant cosecant and cotangent functions on the ti 84 plus ce or any other ti 84 plus graphing calculator but that doesn.

I used google for these calculations for example type in secant 0 70 degrees. 1 divided by sint5 or if you want the cotangent of 10 do the tangent of 10 and then hit the recipricol button usu. Don t get confused and use the sin 1 cos 1 and tan 1 buttons either. Include a few small values around your x value.

My calculator model is ti 30x iis and i need to find the csc cot sec. This is completely different. X 1 you might be trying to do inverse cos sin and tan ex tan 1 sin 1 etc. If you get don t get the answers i did below make sure you re using degrees and not radians.

I m assuming that these are the buttons i need to press. You must use their reciprocals sine cosine and tangent. Secant function is reciprocal of cosine function. Or find cos x store in in ans then do 1 ans 2 0.
