No need to. You answer is correct. [itex]2\sqrt{2}/\sqrt{29}[/itex] would be [itex]\sqrt{4+ 4}/\sqrt{29}[/itex] but [itex]4sin^2(t)+ 4cos^2(t)= 4[/itex] not 4+ 4.hanelliot said:Homework Statement
a = 1/sqrt(29) * (-2*sint, 0, -2*cost)
length of a is?
Homework Equations
The Attempt at a Solution
ignoring 0, we have sqrt{[(-2*sint)/sqrt(29)]^2 + [(-2*cost)/sqrt(29)]^2}. I get 2/sqrt(29) but answer is [2*sqrt(2)]/sqrt(29). Can anyone do this step by step and show me please..
Simple trigonometry check is a process of verifying the accuracy of trigonometric equations and calculations by performing basic trigonometric calculations or using trigonometric identities.
The basic trigonometric functions used in a simple trigonometry check are sine, cosine, tangent, cosecant, secant, and cotangent.
Simple trigonometry check is important because it helps to identify and correct any errors in trigonometric calculations, ensuring accurate results in various fields like engineering, physics, and astronomy.
Some common mistakes to look out for in a simple trigonometry check include incorrect use of trigonometric identities, incorrect input of values, and incorrect use of trigonometric functions.
To improve your skills in performing a simple trigonometry check, practice using different trigonometric equations and identities, double-check your calculations, and seek help from a tutor or online resources if needed.
