WebOct 21, 2024 · So, the function csc (2x) has a period of 2pi/2 or pi. Learning Outcomes. Following this video lesson, you will be able to: Define cosecant, secant, and cotangent ; WebEvaluate csc ( (3pi)/2) csc( 3π 2) csc ( 3 π 2) Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because cosecant is negative in the fourth quadrant. −csc( π 2) - csc ( π 2) The exact value of csc(π 2) csc ( π 2) is 1 1. −1⋅1 - 1 ⋅ 1 Multiply −1 - 1 by 1 1. −1 - 1

WebFor the next trigonometric identities we start with Pythagoras' Theorem: The Pythagorean Theorem says that, in a right triangle, the square of a plus the square of b is equal to the square of c: a 2 + b 2 = c 2. Dividing through by c2 gives. a2 c2 + b2 c2 = c2 c2. This can be simplified to: ( a c )2 + ( b c )2 = 1. WebAs x x x approaches 2 π 2\pi 2 π from the left, x x x approaches a positive number that is slightly less than 2 π 2\pi 2 π and sin x \sin x sin x approaches a negative number that is very close to 0 0 0. cinnamon rolls with apples recipe

WebSep 7, 2015 · What does csc pi/2 equal? Trigonometry Right Triangles Trigonometric Functions of Any Angle 1 Answer Alan P. Sep 7, 2015 csc( π 2) = 1 Explanation: csc(θ) = 1 sin(θ) XXX provided sin(θ) ≠ 0 sin( π 2) = 1 → csc( π 2) = 1 Answer link WebThe value of csc pi/6 is 2. Cosec pi/6 can also be expressed using the equivalent of the given angle (pi/6) in degrees (30°). We know, using radian to degree conversion, θ in degrees = θ in radians × (180°/ pi) ⇒ pi/6 radians = pi/6 × (180°/pi) = 30° or 30 degrees ∴ csc pi/6 = csc π/6 = csc (30°) = 2 Explanation: WebUsing trigonometry formulas, we can represent the csc pi/4 as: ± 1/√ (1-cos² (pi/4)) ± √ (1 + tan² (pi/4))/tan (pi/4) ± √ (1 + cot² (pi/4)) ± sec (pi/4)/√ (sec² (pi/4) - 1)) 1/sin (pi/4) Note: Since pi/4 lies in the 1st Quadrant, the final value of csc pi/4 will be positive. We can use trigonometric identities to represent cosec pi/4 as, cinnamon rolls with apple pie filling tiktok
