15I More on Literal Equations; Pythagorean Theorem

1 5I More on Literal Equations; Pythagorean Theorem A Literal Equations When solving literal equations for a variable, sometimes roots and/or quadratic formula must be used Example 1: Solve D = 5 xy w 2 6 z for w Solution Multiply by 6 z: z D = 5 xy w 2 Divide by 5 xy: 6 z D 5 xy = w 2 Ans w = s 6 z D 5 xy Example 2: Solve 3 w x 2 5 x + w = 0



49 Solving Trig Equations Using the Pythagorean Identities

4 9 Solving Trig Equations Using the Pythagorean Identities 4 9 1 The Pythagorean Identities From the Pythagorean theorem we found the equation for the unit circle: x2 + y2 = 1: From that equation and from our de nition of cos as the x-value and sin as the y-value of points on the circle, we discovered the identity cos2 + sin2 = 1: (15)

107 Trigonometric Equations and Inequalities

10 7 Trigonometric Equations and Inequalities 859 y= cos(2x) and y= p 3 2 y= 1 sin(1 3 x ˇ) and y= p 2 3 Since cot(3x) = 0 has the form cot(u) = 0, we know u= ˇ 2 +ˇk, so, in this case, 3x= ˇ 2 +ˇk for integers k Solving for xyields x= ˇ 6 + ˇ 3k Checking our answers, we get cot 3 ˇ 6 + ˇ 3k = cot ˇ 2 + ˇk = cot ˇ 2 (the period of

credited with bringing pythagore equations outwards While others used the relationship long before their time, Pythagoras is the first to make a relationship between the sides of the distance right-angle triangle of society That's why he's considered the inventor of the Pythagoras equation Pythagoras is
