How to Prove Trigonometric Identities: Example 2 Use trig identities to prove the identity: cscx1+cot2x Step 2:Determine what trig identity is needed, and apply the identity. Otherwise, simplify the expression. 1+cot2x=csc2x ...
Prove the following identities. a. cot x cos x + sin x = csc x. b. cot x + tan x = sec x csc x Prove the following identify tan B/2 = csc B - cot B Prove the identity given. (sin t - cos t)^2 = 1 - sin (2 t) ...
Applyingtrigonometric identities, sinsin 180° – B = sinsin B . Thus, if we are to compute the value in terms ofh, the equation will be: h = b sinsin A and h = a sinsin B . Thus, we can now say that b sinsin A = a sinsin B . Moreover, if we putaandbto the left ...
Step 2: Identify a repeating part of the curve. For the sine function, we can spot the locations of the maximum portion of the curve. In the plot, the vertical lines locate two consecutive maximums. Other Trigonometric Functions Lesson Summary Register to view this lesson Are you a student...
