POLAR COORDINATE GRAPH PAPER. Ideal for plotting the location of points when you know the radial distance (r) and angle (θ) in RADIANS . Great for pre-calculus and calculus students. 150 non-perforated pages with 75 polar graphs on the right hand pages. The pages on the right have the polar coordinate graph paper using radians . Angle measurements at π/12 radian increments. Each page is black and white (not in color). The pages on the left are (half and half): 5 x 5 graph paper with college lined composition notebook paper: - - The upper half of this page consists of the 5x5 graph paper. This is ideal for drawing cartesian (rectangular) graphs, plotting designs, or craft projects. Great for teens and adults to use for math, physics, electronics, science, engineering, computer programming, etc. - - The lower half of this page consists of the college ruled paper. This is ideal for taking notes. Has many uses in the workplace or in high school and college. This graph book can be used in computer graphics, construction, mathematics, aviation, navigation, physics, animation, engineering and radio receiver electronics. Also, useful for teachers and high school and college students.
