since x is negative you use the identity cot-1(x)=tan-1(1/x)+pi. Tan-1(1/-sqrt3) + pi 5pi/6 + pi =pi
Evaluate each expression. | 9 | = -9 because Multiplying and Dividing with Positive and Negative Numbers. ... When the signs of the two numbers are the same, the answer will be positive. When the signs of the two numbers are different, the answer will be negative.
To evaluate an expression with only one exponent, first identify the base and the exponent. Then, apply the exponent to the base by multiplying the base by itself as many times as indicated by the exponent. For example, to evaluate (2^3), you would calculate (2 \times 2 \times 2), which equals 8. Finally, if the exponent is negative or a fraction, adjust your calculation accordingly, such as using the reciprocal for negative exponents.
Yes, when evaluating an expression inside absolute value signs, you first solve the expression as you would normally, following the order of operations from left to right. After obtaining the result, if it's negative, you convert it to its positive counterpart, since absolute values always yield non-negative results. For example, |−3| equals 3, while |4| remains 4.
It appears that the question is incomplete and so cannot be answered. There should be a number (or variable) after "minus".
You cannot solve it though it is possible to evaluate the expression. -5 + 9 * 6 = -5 + 54 = 49

enter the negative first
Your standard Windows calculator (or equivalent in another operating system) will do negative numbers.
negative 4 with negative 3 as an exponent
The expression (-9x^2 - 5) is a quadratic expression in terms of (x). It represents a downward-opening parabola due to the negative coefficient of (x^2). The constant term is (-5), which indicates the vertical shift of the graph. To evaluate this expression for a specific value of (x), simply substitute that value into the equation.
The details vary, depending on the calculator. To specify, for example, 5 to the power -2, you might typically press the following keys: 5 (xy) 2 (+/-) To specifically 10 to a positive or negative power, use the antilog function; for example, for 10 to the power -6: 6 (+/-) (10x)
order of operations:);evaluate powers first, parenthesis second, multiplication and division third (if there is a combination of the two it doesn't matter the order you evaluate), and addition and subtraction last (like multiplication-division it doesn't matter the order you evaluate these two, a helpful tool for this step is to change all minus operations to plus negative).
