This section contains the most basic ones; for more identities, see List of trigonometric identities. These identities may be proved geometrically from the unit-circle definitions or the right-angled-triangle definitions (although, for the latter definitions, care must be taken for angles that are not in the interval [0, π/2], see Proofs of trigonometric identities). For non-geometrical proofs using only tools of calculus, one may us…

WebThe f-theta optics are handy for scanning applications like laser printers. An f-theta lens permits an optical lines scans at a reasonably constant speed which keeps the time between laser dots somewhat constant. Without an f-theta the electronics would need to compensate for a variable time between dots to prevent image distortion.
