For example, a trigonometric function at 270° is the same as at -90°, as their radial lines are the same (you can check it with this calculator) Tan, cot, sec, and csc, calculated from trig identities. Once you know the value of sine and cosine, you can use the following ...
Find the six trigonometric function values of the specified angle. Find the six exact trigonometric function values without using a calculator A. 150^o B. 420^o Find the exact values of the six trigonometric functions of the given angle theta. Find the exact values of the six trigonometric fu...
This tells you which trig function you want: the tangent, since it relates the opposite and adjacent sides and ignores the hypotenuse. From here on, it's easy. Use a calculator or trig table to tell you that tan 60o = 1.73. Then write tan q = opp/adj and you can write the ...
I have problems with downloadable trig calculator. I tried hard to get somebody who can assist me with this. I also searched for a teacher to tutor me and solve my problems on absolute values, function domain and side-angle-side similarity. Though I found a few who could perhaps explain ...
This function has a phase shift. By restating the function as , I can see that the phase shift is 4/3 units to the right. To have table show useful values, I'll change the TblStart to be . Because the variable is multiplied by a 3, I know that the period is going to be ...

INVERSE vs. RECIPROCAL Its important not to confuse an INVERSE trig function with a RECIPROCAL trig function. The reciprocal of SINE is COSECANT: (sin x ) -1 = csc x The inverse of SINE is ARCSIN: sin -1 x = arcsin x The notation is very important - be careful !!
Is arcsin a function? Well, look at the graph of y = 0.82 against y = sin x. Where they cross is arcsin 0.82, and obviously there are many possible answers. So although sin is a function, arcsin is not. Your calculator will give you an answer of around 55°, but that’s just ...
