Trigonometry is largely based on the Pythagorean Theorem which is used to calculate the length of sides of a triangle. The hypotenuse (H) is the longest side of the triangle opposite to the 90 degree angle. The other two sides are known as the base (B) and perpendicular (P) side. The...
It can help you find the length of a side of a right triangle as long as you have an angleθ\thetaθand some info on the other sides of the triangle. Example problems In this chapter, we're actually going to focus on the cosine rule. This means we'll only be working with the "...
Effortless Triangle Solving: Solve for any missing side or angle in a right triangle with ease. Our calculator makes complex calculations a breeze, saving you time and effort. Interactive Triangle Visualisation: Visualize triangles dynamically as you input values, helping you understand the theorem bet...
Calculate the arc cosine of the value using your scientific calculator. The arc cosine, or arccos, is the inverse of the cosine value of the angle. Finding the arccos of the value will result in the measurement of the angle. Usually the arc cosine function will be found as the secondary ...
The magicV I Rtriangle can be used to calculate all formulations of ohm's law. Use a finger to hide the value to be calculated. The other two values then show how to do the calculation. Voltage drop calculations - DC / single phase calculation ...
A polygon is a shape that has any number of straight sides, such as a triangle, square or hexagon. The apothem refers to the length of the line the connects the center of a regular polygon to the midpoint of any of the sides. A regular polygon has all congruent sides; if the polygo...

side. in other words, secant is the reciprocal of the cosine function. consider a triangle abc right-angled at b and θ is an acute angle at b as shown in the figure given below. sec θ = hypotenuse / adjacent side secant can be easily replaced by cos x in this way, sec...
In general, method 1 is better when working with relatively low numbers. For example, a swatch of fabric 4 inches wide and 10 inches long is 40 square inches; dividing this into 144 gives 0.273 ft2. Using method 2 in this case would result in the multiplication of two decimal numbers wi...
Assume that “a” represents the cube’s side length. Thus, the volume of the cube = x3= 10 cm3 By taking the cube root on both sides of the equation, we get ⇒ x = ∛10 = 2.154 cm (approx.) Example 3: Find the value of x, if ∛10x = 2.154. ...
