Use trigonometric identities to prove the identity: cotxsinx=cosx Step 1:Start with the more complicated side of the equation. In this example, the more complicated side is the left side: cotxsinx Step 2:Determine what trig identity is needed, and apply the identity. Oth...
How do you verify sin(x) + cos(x) cot(x) = csc(x)? Using the formulas of trigonometric identities to verify a basic trigonometric function: In trigonometry, there are six basic trigonometric functions in which it became the basis of the trigonometric identities. Therefore, through mani...
How do you prove ((sec x) / (sin x)) - ((sin x) / (cos x)) = cot x? Proving Trigonometric Equation: One of the ways to prove a trigonometric equation is by deriving the right side by simplifying/expanding the left side. This process involves applying identities such as...
Use identities to evaluate a function and find all 6 trigonometric functions: cosec \theta = -5, cos \theta0. How do you prove sec^2(x) csc(x) = sec^2(x) + csc^2(x) ? Given \csc(x) = -\frac{5}{3} with (x) \in Q4 and \cos(y) ...
It is calculated by the ratio of the circumference of a circle to its diameter. circumference = diameter * π or circumference = 2 * π * radius, this means that the diameter = 2 x radius. When is the DEGREES function useful? The trigonometric arc functions return a value in radians. ...
Yes, there are other trigonometric identities that can be used to convert between tan and sin. One example is the double angle identity: sin(2x) = 2sin(x)cos(x). This can be used to convert between tan(2x) and sin(2x)/sin(x).Similar...
A new study published in the journal Historia Mathematica finds that a small clay tablet called Plimpton 322 might actually be a trigonometric table — a tool that allows you to use a single known ratio of the sides of a right-angle triangle to figure out the other two ratios. Based on ...

Know that the conversion formulas that relate the point (x,y) and (r, θ) are: x= rcos θ, y=rsin θ, r²= x² + y² and tan θ= y/x. These are important for any type of conversion between the two forms as well as some trigonometric identities (see Resources). ...
