What does an expression look like in maths?
It is a lot of numbers and letters, combined together with various mathematical operations and functions. Operations such as addition, subtraction, multiplication division, exponentiation etc; functions such as trigonometric ones, logarithms, factorials, etc. An expression cannot have an equals sign (or a less than or more than sign) because then it becomes an equation (inequality). So 3x2 + 2y/sin(x) - 23-x is an expression.
Is 0.9 greater than or less than 0.90?
They are both the same values.
Is 9.02 larger than 9.020?
No because they both have equivalent values
More frequent compounding results in higher future values and lower present values than less frequent compounding at the same interest rate?
Yes
When is the product of two fractions less than its factors?
If the fractions are both proper fractions ... equivalent to less than 1 ... thenthat's always true ... the product is always less than either factor.
How to solve trigonometry problems easily?
To solve trigonometry problems easily, make sure you have a good understanding of the basic trigonometric functions (sine, cosine, tangent) and their properties. Practice using trigonometric identities and formulas to simplify expressions. Visual aids such as diagrams can also help in understanding and solving trigonometry problems more easily.
How do you solve complicated trigonometry questions?
You make them less complicated by using trigonometric relationships and identities, and then solve the less complicated questions.
What is the range of the cosine function?
The cosine function, like all of the trigonometric functions, is periodic about the rotation around a circle. Since the cosine is defined as the adjacent/hypotenuse of a right triangle, you can clearly see that its value can never be greater than one or less than -1 since the hypotenuse is always longer than the adjacent side. It turns out that, indeed, the cosine's range is from -1 to 1, written [-1,1].
Explain why refractive index values of liquids are greater than one?
The velocity of light in a liquid sample is always less than the light in air The velocity of light in a liquid sample is always less than the light in air
Are the probability values always greater than or equal to 0 or less than or equal to 1 or all positive numbers?
Probability values are never negative and are always between 0-1 according to the definition Probability of A= Number of outcomes classified as A/Total number of possible outcomes
What are the values of the square root of x is less than 7?
* == == what are the values of square root of x is less than 7 ? ----
What is efficiency always less than?

What is the formula of a acute angle?
The formula for calculating the measure of an acute angle is not specific, as the measurement of an angle is determined by the degree of rotation between two lines. However, in a right triangle, the acute angles can be calculated using the trigonometric functions such as sine, cosine, and tangent.
Why the value of tan A is always less than one?
The values of tan are limitless (that is to say, within [-inf, inf]). However, sin and cos ratios are between -1 and 1. Think about it: sin = opposite/hypotenuse. Since hypotenuse is always larger than or equal to opposite, sin must always be less than 1. Same with cos.
What is the median of a set of values?
the median is a value of which half of all the values are less than, and half of all the values are greater than.
Is spectroscopic parallax is more accurate than trigonometric parallax for measuring nearby stars?
Spectroscopic parallax is generally less accurate than trigonometric parallax for measuring distances to nearby stars. Trigonometric parallax directly measures the star's slight apparent shift against background stars, providing a precise distance calculation. Spectroscopic parallax, on the other hand, relies on the star's spectral characteristics and assumptions about its intrinsic brightness, introducing uncertainties.
