Proof: sin(a+b) = (cos a)(sin b) + (sin a)(cos b)
In the video, the instructor explores the proof of the trig identity sin(a+b) = (cos a)(sin b) + (sin a)(cos b). In an easy conversational tone, the instructor uses the computer screen as his 'blackboard' and different colors to emphasis his points. For high school students.

3 The water table The water table is a fundamental reference surface in the study of groundwater. It tends to follow the ground surface, rising under hills and falling at valleys, but the gradient of the water table is usually much less than that of the ground surface (Figure 4). Under hills the water table is usually at greater depths below the surf
Introduction The versatility of mammals is a central theme of the 'Studying mammals' series of units, but surely no environment has tested that versatility as much as the rivers and oceans of the world.
