When first confronted with these kinds of evaluations doing them directly is often very difficult. In order to evaluate these we will remember the equivalence given in the definition and use that instead. We will work the first one in detail and then not put as much detail into the rest of the problems.
Most modern HP scientific calculators fall into two classes: The last decent calculator made by HP was the 32sii, an RPN programmable with equation solving and integration.
HP produced the 35s as a successor to the 33s, and at the same time as a celebration of the 35th anniversary of the very first scientific pocket calculator ever made, the HP At the same time, the 35s has a pleasing to me modern look to it. HP calculators have accepted input in the way that problems are actually solved since day one.
Like most of the older HPs, the 35s is an RPN Reverse Polish Notation calculator at heart, although it does have a well-designed algebraic mode for those who prefer this. Power is provided by a pair of CR lithium coin cells, wired in parallel through diodes so that they can be replaced one at a time, without danger of losing any programs, equations, or data you have stored in memory, Although not as tall as older HP keys, they have the classic sloped front, and "HP feel" when pressed.
The keyboard layout is quite good, although I have one small nit to pick, which is that the STO function is on a shifted key. As has been the norm with HP calculators for quite a while now, many of the shifted keys open menus of functions rather than having all possible functions assigned to keys of their own.
As a result, the calculator has far more functions than a glance at the keyboard might suggest. Most of the basic scientific functions are there, including trigonmetrics and hyperbolics and their inverses, common and natural logarithms and their inverses, squaring and square roots, arbitrary powers and roots, and conversion between degress and radians.
MS and decimal hours or degrees. Missing are functions for performing arithmetic directly on H. For example, taking the square root of -2 yields 1. Using the yx key with a 0. Nevertheless, it is possible to perform complex arithmetic once you know how. The calculator can be set to display results in either form as well.
Vectors are entered using the  key, which enters a matching pair of square brackets. The elements of the vector if more than one are separated by commas gold-shifted decimal point. Vectors can be added and subtracted, multiplied or divided by a scalar, or multiplied by another vector to yield the dot product.
There is no cross product function. The base in which they are displayed is independent of the base in which they are entered, so it is always necessary to add b, o, or h after non-decimal numbers when entering them. However, the calculator must be in hexadecimal display mode to allow entry of the digits A through F which is done with the six keys in the row above the ENTER key, which have alpha labels H through M.
The HP 35s can work in fractions, which I find useful in the workshop. One feature of the 35s that I really like is its ability to work in fractions, which comes in really handy in the workshop.
The calculator can display fractions with denominators up toand can be set to always choose denominators satisfying certain requirements for example, a power of 2 when working with inches.
Unfortunately, the interface for these special settings is a bit awkward, requiring the setting of flags. Memories Virtually every calculator has at least one memory in which to store intermediate values.
To store a value, press blue-shift STO, followed by the key with the desired letter on it.Simplifying Exponents Step Method Example 1 Label all unlabeled exponents “1” 2 Take the reciprocal of the fraction and make the outside.

There are lots of things in math that aren't really necessary anymore. These date back to the days (daze) before calculators. Lucky for us, we still get to do them! Once something makes its way into a math text, it won't leave!
(Much like a fungus or a bad house guest.) So, let's go back.
