Lesson 47 drills the radian-only formulas for circular sectors. It covers arc length s equals r theta, sector area one half r squared theta, segment area one half r squared times theta minus sine theta, and the chord two r sine of theta ove
NCLEX-RN Complete Prep Course — Lesson 47: Abuse, Neglect, and Family Violence: Recognizing the Signs and Responding Safely
Sarah Mitchell walks through abuse across the lifespan: child abuse red flags such as injuries that do not match the story, spiral fractures, patterned bruises, clean lined burns, delayed care, and the retinal hemorrhages of abusive head tr
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 46: Graphs and inverse trigonometric functions
This lesson sketches the six trigonometric graphs from memory, covering the periods, zeros and asymptotes of sine, cosine, tangent, secant, cosecant and cotangent. It then explains why sine, cosine and tangent must be restricted to be one t
NCLEX-RN Complete Prep Course — Lesson 46: Cognitive Disorders: Delirium vs. Dementia, Sundowning, and Caring for the Confused Patient
Sarah Mitchell teaches the one-sentence distinction between delirium and dementia, the reversible causes the nurse hunts for, and the CAM, Mini-Cog, and MMSE tools. She walks through Alzheimer's stages and the vascular, Lewy body, and front
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 45: Radians, the six functions, CAST and exact values
Sarah Mitchell teaches radian measure, converting with pi over one hundred and eighty in either direction, and drills the CAST rule for signs in all four quadrants. She covers the memorised exact values for pi over six, pi over four and pi
NCLEX-RN Complete Prep Course — Lesson 45: Eating Disorders and Personality Disorders: Anorexia, Bulimia, Binge Eating, Borderline, and Antisocial
Sarah Mitchell covers the medical dangers of anorexia and bulimia, from bradycardia, lanugo, and amenorrhea to Russell's sign and hypokalemia, and explains refeeding syndrome and why phosphorus is the lab to watch. She teaches structured me
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 44: Exponential and logarithmic functions
