See Answer See Answer See Answer done loading WebInstead, think that the tangent of an angle in the unit circle is the slope. If you pick a point on the circle then the slope will be its y coordinate over its x coordinate, i.e. y/x. So at point (1, 0) at 0° then the tan = y/x = 0/1 = 0. At 45° or pi/4, we are at an x, y of (√2/2, √2/2) and y / x for those weird numbers is 1 so tan 45 ... christine nguyen cyanotype
How do you find theta? Socratic
WebMay 18, 2015 · if you set u = sec θ then you have d u = tan θ sec θ and so d θ = d u tan θ sec θ = d u u tan θ and so now your integral becomes ∫ tan θ u 4 × d u u t a n θ {then you will get rid of you the tan θ in your integral and you will cancel one u. So now you have ∫ u 3 d u and easily you do the integration to get u 4 4 + C WebTrigonometry.
