Relationship between ( r ) and the horizontal component ( a ):<\/h3>\n\n\n\n<p>The horizontal component ( a ) can be expressed in terms of the polar components as follows:<\/p>\n\n\n\n<p>[<br>a = r \\cos(\\theta)<br>]<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>In polar coordinates, ( r ) represents the magnitude (or length) of the vector, and ( \\theta ) represents the angle the vector makes with the positive x-axis. The horizontal component of the vector, ( a ), is found by multiplying the magnitude ( r ) by the cosine of the angle ( \\theta ). This uses basic trigonometry, as the cosine function gives the adjacent side of a right triangle in a unit circle.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Relationship between ( r ) and the vertical component ( b ):<\/h3>\n\n\n\n<p>The vertical component ( b ) is given by:<\/p>\n\n\n\n<p>[<br>b = r \\sin(\\theta)<br>]<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>Similarly to the horizontal component, the vertical component is the projection of the vector onto the y-axis. The sine function gives the ratio of the opposite side in a right triangle, so multiplying the magnitude ( r ) by ( \\sin(\\theta) ) gives the length of the vertical component ( b ). This is a direct application of trigonometry.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Relationship between ( a ), ( b ), and the magnitude ( r ):<\/h3>\n\n\n\n<p>The magnitude ( r ) is related to ( a ) and ( b ) by the Pythagorean theorem:<\/p>\n\n\n\n<p>[<br>r = \\sqrt{a^2 + b^2}<br>]<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>The magnitude of the vector is the hypotenuse of a right triangle whose sides are the components ( a ) (horizontal) and ( b ) (vertical). By the Pythagorean theorem, the magnitude ( r ) is the square root of the sum of the squares of ( a ) and ( b ).<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Relationship between ( a ), ( b ), and the angle ( \\theta ):<\/h3>\n\n\n\n<p>The angle ( \\theta ) is given by:<\/p>\n\n\n\n<p>[<br>\\theta = \\tan^{-1}\\left(\\frac{b}{a}\\right)<br>]<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><br>The angle ( \\theta ) can be found using the arctangent function, which is the inverse of the tangent. The tangent of an angle in a right triangle is the ratio of the opposite side (vertical component ( b )) to the adjacent side (horizontal component ( a )). Therefore, ( \\theta ) can be calculated as the arctangent of ( b\/a ), which gives the angle the vector makes with the positive x-axis.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Consider the vector v with rectangular components (a, b) and polar components (r, \u03b8).
