SOURCE: trying to calculate effective rate

I'm trying to find out how to calculate the effective rate on this machine. Example, I receive a 5% interest on a 4 month basis, what will be my annual effective rate ? In fact, what are the steps to follow ?

Many thanks !

SOURCE: i cant figure out what

Regardless, that is the markings on the SHIFT key on Sharp Calculators. The 2ndF key accesses the functions that are marked on the face of the calculator, not on the top of the keys.

I cannot get the textbook answer (online calculators are also the same as textbook answer) using my sharp calculator EL738: Monthly payment for $184,500 at 6.75% interest semi annually, for 5 year term...

Your result is for the 6.75% interest compounded monthly. The problem states that the interest is compounded semiannually. This makes a difference in the effective interest rate.

A 6.75% APR compounded semiannually gives an effective interest rate of about 6.864%:
Press 2 , 6 . 7 5 2nd >EFF

Converting this to APR gives about 6.657%:
Press 1 2 , 6 . 8 6 4 2nd >APR

If you use 6.657 for the interest rate instead of 6.75 you should get the correct result.

How calculate (1.3)^1/3-1=?

Almost exactly the way you wrote it. Press
1 . 3 2ndF y^x 1 / 3 - 1 =
Of course, that calculates 1.3/3 - 1. If you really mean the cube root of 1/3 then subtract 1, press
1 . 3 2ndF y^x ( 1 / 3 ) - 1

y^x is the shifted function of the DEPR key.

Show two decimal places

Input the following and try:
  1. Press 2ndF and . the point button. This changes the screen to FIX DEG
  2. Press 2ndF +/- 2 Answer shown is to 2 dec. pl.
  3. If you want it to 5 decimal places, Press 2ndF +/- 5 answer shown is to 5 d.p. and so on
For normal, just take calculator out of FIX so just DEG shows.

Couldn't find you a YouTube video, so text will have to do.
